1) I suggest that poison cloud actually adds toxic to the enemy and not only poison and that its cd becomes 2 or 1 round instead of the actual 3.

Reason: the mystery right now is wholly useless and its cd makes no sense. adding toxic (that is what you experience in hanzo sa) would make it at least a bit more appealing.

2) I suggest that you modify poison tai to take in account the fact the eventual enemy may be immune to debuffs, something like that if the enemy is immune to debuffs then the damage landed on it by tai and nin/tai effects is increased by at least the same quantity anbu special tactics grants.

Reason: poison is nice and very useful in many situations, but while is a pretty nice addition when you fight not immune enemies is wholly useless when you fight immune ninjas. Modifying the passive to become at least decent in any situation would be indeed the right thing to do considering the fact is the only buff af grants to not water ninjas and is the only main that miss something that work in any situation.

3) I suggest also to rethink reserve seal and to actually let azure fang self heal with it even if is under ignition or to bring the critical bonus per stack to 3%, like kushina habanero, or to actually let her first remove debuffs and then heal with healing standards or mysteries that target her when that passive is selected.

Reason: The reason why none uses this passive is because does not reach at all its intended purpose and that is because is too easy to get ignited and wholly see denied the healing part or because the quantity of critical rate granted is too low to think to trade it for one mystery every round, for poison tai or even for the clone.

4) I suggest that water style - flowing whip becomes the same as the clone one and that monster strength bonus to damage coming from hp part becomes similar to dbp hidan's.

Reason: taijutsu attack high critical property makes it pretty fearsome with neurotoxin while healing jutsu does its job pretty well, so why should i select the other two standard attacks if they are not even remotely close to the first two? Water style - flowing whip does pretty nicely its job when used by the clone but the version used by azure fang herself misses wholly the goal because does not own the high combo rate property that would make it comparable with taijutsu attack and healing jutsu in usefulness. About monster strength i understand the fact that owning the high combo rate property with high float is appealing, the problem is that the self damage endured is meant to work in synergy with reserve seal that, sadly, as i explained before, does not reach its goal at all as is now, so, the part that should make it appealing when not in synergy with reserve seal is the additional damage landed based on actual hp vs total hp (that works like dbp hidan or naruto 4 tails or fuguki), but here again the problem is that the % of hp that becomes damage is too low. Even at 4% hp the additional effect is just a 20% of the total hp (before any reduction comes in play of course). I do not say to make it as op as dbp hidan or lee gate of joy one, but at least half that effect would not be bad.
