—Mua's Defeat Quote
Subjective: The following part of this article is subjective to the editor's writing. Therefore, it may not work for everyone.
Whether or not the player is capable of surviving multiple blasts from Mua's Fenrir tome, the Warp (and to a lesser extent the Reserve Staff) he holds is simply too precious a commodity for the player to pass up. Mua should be immediately silenced if at all possible,even if the use of the Barrier Staff is necessary. The player will have few other high-priority targets for the Silence Staff anyway: most bosses are positioned on a gate or at Throne, and will be immune to status conditions as a result. The few remaining bosses who do appear on the field all have at least one non-magical weapon, and should be berserked or put to sleep instead. Whatever the case, Sleuf joins with just enough Magic to silence Mua, after the effects of a Barrier Staff boost.
Once silenced, the otherwise terrifying Mua poses no more of a threat to the player's army than a Level 1 Civilian would.
