Since the last patch it seems like anything that sees through bard invis, sees through SoS. Was it intended that SoS was to be useless in this expansion?
Bard invis is both. And is seen by -some- things, which is to be expected, invis isn't supposed to allow you everywhere. The problem is that SoS is being seen by basically everything that sees through bard invis and that's not normal. SoS is supposed to cover 99% of mobs. The way it is now, it's useless.
Which mobs? The only mobs I was aware were the Drolvargs on the 6th floor of ToFS … which are now spawning on the 1st floor as well (which will hopefully get fixed next patch). And there is at least one live named (Bloodmaw in GD) that may or may not see SoS (haven't tried it with a rogue). But I've used a rogue for collection searches in all zones other than ToFS without issues.
Which mobs? Only things I've found in all of ToV that see through SoS2 are on floors 6 and 7 of ToFS (plus the temporary invaders on the first floor).
Interesting. I had them aggro me while IVU so I assumed incorrectly they were flagged as live mobs. Not recently as they now appear to be extinct.
I was using my rogue on day one of ToV to look for collectibles. Had SoS on and came up to a derv from behind, conned it, and since it was indifferent I ran on past it. As soon as I got in front of it, WHAM!...it started attacking me. Luckily, I was able to get far enough away to hit escape. When I went back to check it, I realized that I got the indifferent message because I was sneaking and behind the mob. From the front, it was scowling with SoS on.
Yeah they do. It's a bug, it's been posted. - TOFS Floor 6 and above. Hardened Giants. Sprites. Queen Dracnia can all see invis/ITU/SOS2. Someone said Velks spiders can spawn seeing it too, but I never saw it personally.
The Hardened Giants I tested 100% do not see through SoS2, just tried three of them at the wizard spires while writing this post. Did three entire laps of Velks and couldn't find anything that wasn't either undead (didn't see IVU) or live (didn't see normal invis), nothing except some non-kos Dwarves were able to see me.
ToFs mobs, Herbalist? in Mines, Giants & Dervs in GD, queen in CC. There's a couple more. The big thing was ToFS because it completely negates their ability to CR even on the 1st floor, though I was unaware of it being because floor 6 mobs were spawning there.
The spiders in velks can definitely spawn as see IVU, found a couple unexpectedly while gathering collections.
