So I was reading through slayer and my favourite class (Necromancer) and realized that the thrall mechanics gives a Slayer pretty much infinite On the Hunt Triggers. Thralls are codified as creatures with 1 hp which are brought to 0hp by pretty much anything. This means that a slayer can use their reaction to go On the Hunt almost whenever one is destroyed.
Now there are some limitations, as far as I can tell Necromancer abilities that destroy thralls shortcut hp so don't meet the requirements of being "reduced to 0hp" that On the Hunt Stipulates. But any form of damage from strikes, aoes, breathing too hard, looking at them for too long ect...is going to proc an On the Hunt Reaction.
It feels...like a really broken interaction and hey! maybe in the final version of Necromancer they codified thralls to work differently but at least in these two playtest versions this synergy in strong.
