(Note: I wrote this post for my guild a year or so ago to inform them about promised heals and interposition, which some members were not aware of. I thought I would share it here as some still believe that these spells are "useless," mostly due to how healer mercenaries use them. Though not all clerics will find these spells as useful as others do, I hope most will agree that they can be useful when used by a cleric with a brain and that players should avoid keeping them blocked during raids.) Cleric Promised Heals/Interposition (Information and Usage) A few years ago, clerics received an ability called 'Promised Interposition' that provided a significant incentive to use heals from our 'promised' delayed heal spell line. The intent of this post is to inform guild members about Promised Interposition, hereafter referred to as 'PI,' and how it makes promised heals, sometimes referred to as 'PR,' worth casting. If you don't want to read the rest of the post, the main point is that promised heals/PR should not be blocked by anyone in raids, provided that there are clerics and/or druids in the raid willing to use them (and most of us here are). Please take a few seconds at the beginning of each raid to unblock them if you have them blocked for group play. What is PR? PR refers to the cleric and druid promised heal lines (most recent cleric version shown below): [58680/4814] Promised Redemption Rk. III Classes: CLR/113 Skill: Alteration Mana: 1727 Target: Single Range: 200' Resist: Beneficial, Blockable: Yes Focusable: No Casting: 0.25s, Recast: 15s, Timer: 12, Rest: 1.5s Duration: 18s (3 ticks), Dispelable: Yes 1: Cast: Promised Redemption Trigger III on Duration Fade 2: Stacking: Delayed Heal Marker (53802) 3: Stacking: Block new spell if slot 2 is 'Delayed Heal Marker' and < 0 4: Stacking: Overwrite existing spell if slot 2 is 'Delayed Heal Marker' and < 0 Text: You are promised divine healing. Imbues your target with the promise of a *#1#1 point heal in %z. Will heal for *#1#2 hit points instead if the target is under 20% of its maximum at that time. [58683/19758] Promised Redemption Trigger III Target: Self Resist: Beneficial, Blockable: Yes Focusable: No Casting: 0s 1: Increase Current HP by 53802 (If HP Above 20 Percent) 2: Increase Current HP by 69943 (If HP Below 20 Percent) Text: The promise of divine healing is fulfilled. Heals you for #1 hit points, or for #2 hit points if you are below 20% health. When this spell is cast, the target receives a buff in their spell window with an 18 sec timer. When that timer has expired, they receive an instant-cast heal. The heal is focusable and can critical heal depending on the target's healing AA. Because of the long timer, these heals do not always land. When they do, however, the results can often be significant: [Sun Aug 11 20:32:21 2019] Foob is infused by divine healing. Foob healed itself for 240544 hit points by Promised Remedy Trigger III. (Critical) [Sun Aug 11 20:32:21 2019] Foob is no longer berserk. The cleric version technically can heal more if it lands on a target with less than 20% of their health as well, as it probably did in the above case bringing Foob out of his berserk state. The advantage to these heals is that they can land on the target when they are out of range of the cleric (when kiting, for instance) and provide an extra layer of healing in addition to the healing they are receiving from the cleric. A cleric can cast a promised heal on the tank on engage before he has taken damage and then begin casting fast direct heals. At some point during the casting of those direct heals, the 18 sec timer of the promised heal will expire, providing the tank with an instant heal. This has the potential to increase the amount of healing to the tank when combined with direct and duration-based healing like elixirs, making it easier for the cleric to keep him alive. It also could land when the tank does not need a heal, as he could be at full health when the timer expires. The thing about promised heals, however, is that they are often the best healing action a cleric can provide at a moment when direct healing is not necessary. Using the example from above, at about 2-3 seconds before engage, a direct heal would be a waste to cast, especially our fastest heals, which land in 0.5 sec. If a cleric spends 0.8 sec casting a promised heal instead, then the tank has 18 sec before that heal lands. While it still might not land and end up being wasted, there is a better chance that the tank will need a heal 18 sec from now (when he is actually taking damage) than 2-3 sec before engage when he definitely does not. Promised Interposition, or PI, is another benefit that a tank receives from the casting of the promised heal, which I will cover next. What is PI? PI is an additional reactive heal that a target receives with every promised heal cast. [16036/49511] Promised Interposition VII Classes: CLR/254 Skill: Melee Target: Single Range: 1000' Resist: Beneficial, Blockable: No Stacking: Promised Interposition 7 Focusable: No Casting: 0s Duration: 18s (3 ticks) Song, Dispelable: Yes 1: Cast: Promised Interposition Heal VII if 15000 Melee Damage Taken in Single Hit 2: Cast: Promised Interposition Heal VII if 15000 Spell Damage Taken in Single Hit Triggers *#1%n, healing *#1#1 health, if you are hit by a direct damage spell or melee attack that deals $1 or more damage. [16053/49514] Promised Interposition Heal VII Classes: CLR/254 Skill: Melee Target: Self Resist: Beneficial, Blockable: No Focusable: No Casting: 0s 1: Increase Current HP by 40000 Text: Your promised interposition is fulfilled. Heals #1 health. In addition to the buff with the 18 sec timer in their spell window mentioned earlier from the promised heal cast, the target will receive another buff in their song window with an 18 sec timer. What makes this buff different is that if the target receives at least 15000 damage in a single hit (either melee or spell damage), they will instantly receive a 40000 point heal, which is focusable and can crit based on the target's healing AA. Here is what that heal is capable of: [Sun Sep 20 18:40:07 2020] Rune's promised interposition is fulfilled [Sun Sep 20 18:40:07 2020] Rune healed himself for 30151 (138756) hit points by Promised Interposition Heal VII. (Critical) [Sun Sep 20 18:41:18 2020] Rune's promised interposition is fulfilled [Sun Sep 20 18:41:18 2020] Rune healed himself for 82438 hit points by Promised Interposition Heal VII. [Sun Sep 20 18:41:51 2020] Shmid's promised interposition is fulfilled [Sun Sep 20 18:41:51 2020] Shmid healed himself for 63170 (164738) hit points by Promised Interposition Heal VII. (Critical) <-- even higher total on knights with healing aa Note that it can, depending on other healing buffs, crit for up to 165k. Though it might seem small, keep in mind that this heal is damage-reactive, meaning it happens at the point damage is received. Unlike the delayed promised heal itself, which isn't too accurate because of the 18 sec. timer, this PI heal is incredibly accurate. It will almost always be the first heal that lands on a target, provided he is taking enough damage to reach the 15000 damage threshold before the 18 sec timer expires. Unlike the delayed promised heal, if a target does not take 15000 damage in 18 sec., then they receive no healing from PI -- it just fades without doing anything. Taken together, then, PI and PR provide a target with an instant damage-reactive heal that is pretty much guaranteed to counter the first 15000 points of damage they receive in most cases, and a potentially useful heal that will land 18 sec. later, all in a spell that can be cast in 0.8 sec with a low recast timer of 16 sec. How to Best Use PI/PR PI/PR is useful when direct healing is not necessary but a cleric still wants to provide a healing action to the target. It can be used before engage, as described earlier, so that the target is protected from the first 15000 points of damage that land on them through the PI heal and could potentially receive another 53000 or more (before focused effects and critical heals) 18 sec. later. In this way, a cleric can provide support to a target they are not actively healing. If I am focusing most of my direct heals on Main Tank A, I can provide Off Tank A/B/C/D with PI/PR in between those heals so they gain some healing support from me. It can also be useful when solo healing if you have a good feel for the incoming damage, allowing you to squeeze more healing in than is possible with just casting direct heals. Timing, however, is incredibly important. You do not want to cast PI/PR when direct heals are needed because they are not an adequate substitute for those. This is also why mercenaries are terrible at using PR (besides the fact that they do not have access to PI) because they are not able to identify when it is safe to cast PR and will cast it to maintain it on the target, regardless of the target's immediate healing needs. It is especially useful when you know the target will be out of healing range soon, which happens when kiting or dodging an emote. Wherever the target ends up, they will receive both the instant heal of PI and delayed heal of PR regardless of how far they are from the group. Stacking Concerns and Differences Between Cleric and Druid PR The druid version of PR technically has a higher delayed heal marker (55919 compared to cleric 55207), even though the base heal value is actually lower. This means that it will overwrite the cleric version, while the cleric version cannot overwrite the druid version. The cleric version will overwrite another cleric version (assuming they are the same rank or higher). Or, to summarize: Druid PR -----------------> Cleric PR ----------> Cleric PR overwrites/blocks overwrites The problem is that druid promised heals do not give the target PI, so a target will only receive the delayed PR heal instead of both the instant PI and delayed heal of the cleric version. For this reason, druids should not cast promised heals on tanks unless they are in a tank group and the amount of clerics in the raid doesn't allow them to cover all of them. That doesn't mean that promised heals can't be used within a druid's own group or on targets (casters and melee) who are unlikely to receive promised heals from a cleric. Though cleric PR overwriting another cleric's PR is a problem as well, it mostly means that the target will have to wait longer for the delayed PR heal because every time a PR is overwritten, the target receives a fresh timer for the delayed heal and a new PI heal. PI heals are used up very quickly if a target is taking active damage, so even if PR is chained on him by multiple clerics, it's possible that he will receive a PI heal from each of them even if the PR heals keeps getting delayed with a new timer. Overwriting of PR is not ideal, because you want a target to benefit from both heals, but in a typical fast-paced raiding environment ensuring the target has a fresh PI is usually a more immediate concern as it (compared to the delayed PR heal) has a better chance of being useful. For that reason, I am not as concerned about clerics overwriting each other but if you notice a particular tank receiving a lot of PI heals (Pano has created a trigger you can ask him for which will tell you when it has fired and on whom), that's an indication that you probably could be casting it on someone else. Blocking Promised Heals (and Why You Shouldn't) Typically, most players block promised heals when grouped with healer mercenaries because, as mentioned earlier, they don't use them well and blocking them prevents the merc from using them at the wrong time. As I hope this post has demonstrated, clerics and druids who are knowledgeable about promised heals can use them more effectively than your merc, so there is no need to block them on raids and doing so actually makes their job harder because you're removing a potentially useful tool from their toolset when healing you. Simply put, there is no good reason for anyone who might be healed directly by a cleric or druid at any point during a raid to ever have these blocked.
