He bleeds normal good ol crimson blood.

As for his powers, he’s a White/Green essence user, which gives him the ability to manipulate lesser lifeforms and nature like animals, plants, etc. He’s an expert at sword combat, and is noticeably agile, hitting him is quite the challenge. He’s also partially a Null, he can do things with shadows/darkness, like turning himself into a puddle of blackness, or turning his arm into a large void tendril to thrash with. A final thing to add is that if he’s hit in his mask, the damage is negated or reflected depending on the strength of the attack.

I’ll link you the file in a second.
