My opinion on the stuff?

The eitr cost on most things should be heavily reduced, especially cause the eitr regeneration, even with the full mage set is absolute garbage. Frost staff seems fine, but the flame staff is just too much, even with full eitr, you shoot like 6 times and you are empty and can't do anything for the next 20 or so seconds if you want full eitr again.

The blood magic staves are nuts in consumption and the skeletons do jack doodles at low levels of blood magic and get killed in 2 seconds. Put down 2 skellies and buff them with a shield?, not enough eitr to do that at once and it also costs a ludicrous amount of health.

Leveling the stuff?, we should have early options for magic, or the exp requirements should be toned down for it. Tried leveling up blood magic for an hour or so and it got to level 7... those are supposed to be the early levels, early on i level up blunt weapons to 10 in that amount of time without even trying.

Queen fight with magic is one of the easiest fights in the game though, i went in with 3 eitr foods, didn't know what to do against me.
