I have it to 200 and it's not doing the burst damage when summoning a trinket pet or shielding any pets. Idk if I'm doing something wrong or artifact is glitches
its in mid range you have to get close for the big hit that comes from summoning the pet. you also have to space them out cant summon say pet then henchmen back to back you need a gap of about 15 seconds or so between them
You need to be in combat. (Wait until you see your icon go red.) You need to use a combat pet. (It doesn't activate with the henchmen.) You need to be about EMP range from the enemies. (This only affects the damage, the shield should go off at range.)
You are correct and I thought so too, but when I tested it during the double xp week, someone asked me which activated. So silly me, I went and tested the one henchmen that doesn't work. Batdrones Who Laugh. lol They are bugged, apparently. I tested Robins and they work fine with it.
