Turns you into a panther: you run and attack faster and land more criticals. Press it again to turn back.
In form: run +40%; you dodge 11% of hits, +1% per level; attack speed +12, +2 per level; critical +6, +1 per level.
Damage in form: 79% of normal, +4% per level.
Weapon: 26 attack, +6 per level. If 40% of your magic attack is higher than your attack, that counts instead.
Pounce (level 1): leaps on the target and stuns it. 155% of attack, +15% per level. Stunned for 0.9 s, not on bosses.
Claws (level 3): three scratches of 60% of attack, +5% per level. Then Bleeding for 6 s: 18% of attack per second, +3% per level. After the third scratch the panther leaps back 2.5 tiles and for a moment nobody can hit it.
