Spell and Roulette name suggestions.
Spells first.
Since YoshiP wasn't sure what to name the new AoE Fire and Blizzard spells I would like to suggest that any Single target spell just be numbered. Ex. Fire 1, Fire 2 etc. For AoE spells let them be the Fira, Firaga, Firaja, Firasa, then finally Firaza... if we get that high to begin with. (I believe FF12 was the first game with -ja spells and I remember KH3 having Stopza so... that's where I got them. Not sure where I saw Curasa tho but meh)
Roulette
For the Level 50/60/70 and now lvl 80 Roulette, how about just calling it Previous Capped Dungeons or Past Level Capped Dungeons?
