I couldn't miss the chance to practice my drawing!
Ultiga (often misspelled as Ultimaga) deals incredible damage to nearby enemies and stuns them. It is cast by stacking all six types of magic: Fire, Blizzard, Thunder, Cure, Raise, and Clear. It can be cast only in Multiplayer.
However, if one is very quick and has used a Scratch Card from a won Magic Stack series, Ultiga can be cast even in single player.
