1. Make Illusion-Mirroring Jutsu 2 round cooldown instead of 3.

If they make shark bomb a 0 rounds starting cd with a cost of 20 chakra instead of 40 i could be ok with it.

2. Replace one of his standard attacks with one similar to Lightning Main's Calm Mind.

I'm ok with it as far as healing jutsu (the 2nd standard attack) first removes debuff and then heals and if may be used even if azure fang is under sleep/immobile/chaos effect only on herself

3. Make his clone attack on it's own, using Scarlet Blaze's Fire Style-Bomb Blast. Make it have 60% of it's owner HP instead of 40%.Basically same % as Water Main's version of it.

If water main clone can be used together with poison tai or together with experimental ninjutsu and gets 100% of the original main stats i'm ok with it.

4. Make Ninjutsu Urge leech for 25% and improve ninjutsu by 25%. Basically same % as LM's version of it. Keep Genjutsu Mirror where it is, his only redeeming passive.

If nature energy gathering grants also a selfhealing of 12% total hp every time azure fang gets chakra and if the ninjutsu boost goes also to healings i'm ok with it.

5. Last but not least, give him Immunity Passive to 3 fire ninjas and 100% resistance, name it Root of Fire and replace Death Mirage with it.

If reserve seal increases crit chance by 4% per stack and selfheals also if azure fang is ignited i'm ok with it.

Just know that what i asked as compensation is more or less what is needed to rebalance what you asked.

This can't wait a couple of years, a couple of weeks/months maybe. xD
