He can solidify when he wants, but if his mask is grabbed he is forced to solidify, if digested his body just deforms into go, and reconstitutes elsewhere.
As a ghost, he has many abilities he loves using to screw with people, those include:
1: Intangibility
2: Invisibility
3: Entering Dreams
4: Eating Dreams
5: Eating Emotions
6: Making copies of himself
7: Possessing People
8: Using Dark energy to project sadness on other people, so he can feed.
He tends to be a nice kid, treating others how he feels they should be treated, this of course leads to some hilarious moments, since he also tends to be a bit of a joker, pulling pranks and making jokes on those that deserve it, or sometimes those that don’t. When speaking of his niceties, you must of course speak of the other times, when he is angry, he gets mean, really mean, to the point he wants to be alone, the boy hates being made fun of, or being hurt, or bullied, he will do anything to make that stop, even resort to violence, in a combat situation its different, he instead is calm and focused, ready to do what he needs on the drop of a pin, and he's calculating, knowing when to taunt, when to not, he doesn't mind pranks being played on him by the way, infact he loves it, april fools day is his favorite holiday, for a reason, cause it brings laughs to everyone, which is his goal, to make everyone laugh and have a good time.
Vore Battle Abilities:
Passive:
Flight: well, he is a ghost, so flying is a must +3 on hold breaks because he's hard to hold
Sleepy Touch: Every turn he has a hold on you, you gain 1-D token, for each you get you get -1 on each roll, and once you get 10 D-Tokens both players roll, if Corvus wins his opponent passes out for three turns or untill Corvus is forced from their dreams, if the opponent wins they lose all D-tokens and Corvus's mask falls off, opening him to anything.
Combat: Corvus doesn't really focus on attacking on the material plane, instead focusing on lulling his opponent to sleep and devouring them in their dreams.
Abilities:
Intangibility: He can turn intangible, instantly slipping from any hold on him, thats what you get for grabbing a ghost, can only be used once every four turns
Invisibility: He can turn invisible, giving him a +4 on all grapple rolls or attack rolls, can only be used once every three turns
Shadow Ball: A simple ability that generates sadness in whomever it hits, awards 2 D-tokens and opponent gets -2 on all rolls
Clone Creation: His ultimate defense against master predators, all three clones have five health and act independantly of Corvus himself, but share abilities with him.
Possession: He can possess his enemy, this is his favorite ability, for each turn their possessed they get 3 D-tokens, they need to role a 13 or higher to escape his ghostly possession.
Mask Pranks: His mask, when pulled over his face, becommes a weapon of fear, when pulled up his opponent will see their greatest fear, if the opponent rolls higher then Corvus on this, Corvus's mask falls off, if they roll lower, they are rewarded with four D-tokens
Now we get to his mask....his mask is the center of his powers, when removed, he solidifies and becomes a very easy meal, its also the secret to his powers within the dream, when removed there is forces him out and releases the opponent from their sleep, removing all D-tokens.
Now for the Vore moves, they are a doozy....
When in the dreamscape, Corvus becommes much more powerful and omnipotent, he can preform all types of vore he wishes, including a few that are unprecedented.
