Why won't it let me change my magic to cup of shell I need complete this quest but I select it on magic tab and when I hold g it's just dragonshout fart I made sure cup of shell was selected still not working. Every time I hold g it's the dragonshout fart. I reinstalled the game like twice still no hope. I was really getting into this game. Btw I'm on pc

Are you using E to cycle your magic spells outside of combat? The magic UI screen is not meant for picking which spell to use in the world. It's simply to show what spells you have and what they do.

 

When in the world, you use Q to cycle your non-magic tools (shoot, probe, etc.) You use E to cycle your magic spells.

Omg Thank you so much!!!
