Regarding AoF, kills and passive reactivating
Disclaimer: Those are only theories, but I try to stick to stuff I was able to confirm countless times.
A "kill" counts if and only if the now dead character was the main target of the attack (bug)
Meaning if you target Wrath and Undead Rescuer dies as a result it doesn't count.
Same thing if you target Corrupt Rescuer with Wrath, not killing the former but another toon, it doesn't count either.
In both cases, if you have AoF, no extra turn. And If your opponent does have AoF he can still get one.
This bug can add some light on some reports that are off the mark.
In some occasions, passives supposed to work only at the start may be reactivated during the fight
Resurrecting a character can achieve that, but is rather erratic. Definitely a bug.
Getting rid of the "passive disable" debuff also can. If passive wasn't activated before, is it a bug?
From my experience, may not happen at all or only partially.
For example resurrecting Desert Marauder might
- do nothing
- grant perfect hit for some allies but not necessarily all of them
In the case of AoF, it's a wild guess but I think same happens.
Some characters on the team may now trigger extra turn again while others won't.
Without a better knowledge of how it actually works, hard to tell.
Does anyone have a better theory?
Regarding endure and death
Permadeath explicitly counters endure, making it sound like reaching 0hp with endure on could be considered as a kill.
Thus getting an extra turn with AoF might be working as intended and not be a bug.
