Agni (fire punch)

Cursed Flames. Agni is on fire as a result from a high level mage

• when on fire Agni's Strong Regeneration is hindered 
• when on fire Agni's physical attacks do extra fire damage
• Direct touch (E.g. unarmed strikes, grapples etc.) cause the creature to touch Agni to take 1d6 fire damage for 1 turn
• the flames can be put out by 8th level dispel or 2 7th level or 4 6th level and so on
• when another creature is hit by an attack while Agni is on fire they take the Fire damage again once their turn starts for 2 turns 
• Agni can not wear clothes nor armor while afflicted by Cursed Flames nor can he use any tool or weapon other than his limbs

Strong Regeneration. Agni constantly regenerates on his turn unless 

• 1d20+8 (unhindered)
• 2d8 every other turn (hindered)
• 1d4+1 every other turn (further hindered)
• any limb that is torn off, cut off, ripped off etc. regens after 1 turn +(number of hindrances) if under influence of Mind Haze this is instant 

Resurrection. Agni is someone cursed to never die 

• if Agni is killed he will revive to 75% full hp after 2 turns 
• Resurrection can be temporarily halted through freezing him or destroying his brain
• if you absolutely destroy this man mentally you can completely stop resurrection until he recovers (if he recovers in time)

Nude. all the clothes Agni tries to wear burn or melt off

• weakness to slashing and psychic damage
• resistant to cold (while on fire) and poison damage 
• immune to fire damage (while on fire)

Mind Haze. 1 time per long rest Agni spends his next 2 turns unable to move or take any action he fails any and all roles and saves but this skill is not cancelable. After the 2 turns regardless of Agni's state his regeneration is multiplied by 2.5x (round down) and his fire damage is doubled. Agni in this state gains +2 to hit but his Int, Cha, and Wis all drop to 8 

Limb from Limb. Agni rips of an arm(-1 to Dex) or leg(1/2 move speed) to use as a weapon
