I think we should just remove Lucid Dreaming entirely, and compensate it's regen-per-min effect with buffing things like Assize's MP restore effect, natural MP ticks, or both. It's not an interesting button, it only serves to make 'pressed it and died right after' more punishing, and it's effect of 'restores 3850MP per minute' (or, averaged out over 1min, 192.5 per 3s, less than the base regen amount of 200mp per tick) is not worth having a hotbar slot dedicated to it, especially given the main opposition to several good suggestions has been 'we don't have the hotbar space for something like that'

Remove Lucid, make filler spells cost nothing (or like, 100mp), use the hotbar slot for something more interesting
