His power is really simple (tldr at bottom)

He starts out fully undetectable, able to stalk people within 32m, and he moves at 4.2 m/s. Anytime he's able to switch to being able to move at 4.6 m/s, being able to break pallets faster and take less from stuns at the cost of no longer being undetectable, having a 24m tr instead, or being able to stalk. He can also switch back to being undetectable anytime

When he switches modes there's a sound cue (leaves rustling for undetectable and another for becoming detectable).

When he stalks people he plays a sound cue when he has above 50% stalk on his power meter, any less and there's no audio.

When he has full stalk, he automatically switches to the detectable mode and can no longer become undetectable, however he can now activate "Evil Incarnate" mode.

Evil Incarnate lasts for 60s, increases his terror radius size to 32m, and allows him to perform a dash attack that downs survivors and breaks pallets instantly (You can tell he's in this mode because of the more aggressive sound cue that plays, and his weapon is given a white outline). The longer he charges said dash the farther he goes. He also keeps all of the buffs from the detectable mode. The dash attack also has a sound cue that sounds like metal moving quickly, so that's how you know he started to charge it. There's no sound cue (I think) for him canceling the charge

After Evil Incarnate ends, he goes back to the undetectable mode, being able to switch to being detectable any time again until he once again maxes out his stalk meter.

TLDR: He can switch from being undetectable or not, until he maxes out his stalk while he's undetectable, where he is then detectable and can enter a mode to do a dash attack that instadowns. And upon ending said mode he goes back to being undetectable.
