@TigerKnee:
Funny last comment, I used to be a high-end HoN support
However, I got more stuff from your comment, and thank you for it:
1) Doesn't work on undead part is deffinitely something I'm not/wasn't taking into account. Mana Burn and Poison are also a problem (because it's a regen fighting boon).
2) What you mean by isn't reliable is that you can't prep it, which is something the dev's can decide to undo on a whim (and are being asked to). Assasins don't have it, what they have takes up an inventory slot, isn't compatible with getting all of Taurog's stuff as smoothly and costs mana to use. And wether I'd prep it on every run that doesn't have 2 confirmed undead bosses is what I'm trying to figure out, because...
3) If it really works the way I described it in the OP (the effects, not the tomfoolery), then it's an equivalent of as many mid-fight level up heal (bloodswells + schadenfraude) as long as the boss isnt undead/poisonous/has mana burn. Poison can be worked around with a poison ward or HALPMEH, and mana burn can be worked around with a Soul Orb or simply not be necessary - you're still getting a bloodswell (depending on your resists same as up to X death protections).
Why would you bother wasting exploration on anything else, really, from a pure cost-effect-effort perspective?
I'm not saying it's necessarily gimped, but if it rewards reduced gameplay in the sense that "if it works" then it works like a bunch of "bloodswell + schadenfraude" asspulls as long as you have exploration, it might explain why I don't think of the current TT unprepabble. I was prepping him all this time.
@Nandrew:
please, excuse the poor taste, and allow this thread to live, I'm done with the other one, I swear. You wouldn't believe, but this is about more than TT, and is allready usefull. Ignore it please, if it gets as much as one "lurker" coming out with his view of tiki without me scaring him off with huge text walls, as well as more pro perspective, it'll be incredibly worth it.
