Traven here uses crystal magic. It's very versatile, he can shoot crystal beams, projectiles and barrages, summon crystal storms and meteors. He can even coat his staff in crystals extending its reach and using it as a blade. 

He has a small army of undead constructs. A few huge beasts and long range mages, rest are basically foot soldiers. They won't go down until their core is destroyed or they can no longer move.
________________________________________________

His non- crystal spells are:

Wall of Twisted light - will block all and any magic, useless against physical attacks and costs alot of mana

Pestilent mist - poisonous mist that is deadly once inhaled, only the caster is immune to it

Misty dash - quick teleport, short distance, can't pass through solid objects

Mirror image - caster designates the locations and 5 copies of them spawn and start shooting spells, caster can change places with the copies, each copy goes down after 1 hit

Exstruor - a form of blood magic, creates a copy of the caster, this copy is not as strong as the caster and can take a good amount of damage, it can use most of the casters spells, can't be used with Mirror image

Traven has physical capabilities slightly above that of a human in peak physical condition. His body is very durable to most damage.

Since he's an undead his main weakness is holy magic or weapons. Each hit by those causes immense pain and will force him to lose his "human" form if damaged enough. The next best bet is fire though it is not as effective.

In power scaling I'd say he's City level.
