A haze panther

Level 39-41 · Puma · Warrior · The Wakening Land

Invisible when not attacking in melee range. Need see invis to see them but can track them without. Very rare, not certain they're on the A panther spawn table but after killing 121 regular panthers I've only killed 15 haze panthers while keeping my eyes peeled for them on the track window and only one dropped a skin. Not uncommon to scout the entire zone and see none up so you'll have to work for them.
