Remove Spell From Spellbar
 

I accidentally keep right clicking on my spells in the spell bar which is removing them while I'm mid-fight.

It's been a headache. Is there a way to lock the spells to the spell bar?

no, how are you right clicking them? try different key binds

I also am a filthy mouse clicker. One option if you wanna sacrifice your hotkey bar is just making 1-8 your spells then I guess if you right click it will only bring up the context menu which is less of a setback than a spell being gone (I'm pretty certain but it's not right in front of me so I could be wrong but I feel confident). Or if you can develop a new habit, just learn to Alt 1-8 for your spells but I know how habits go so I don't really have any justification for telling you to get gud or anything like that

Physically break the right mouse button.

Hope this helps! (:
