Formulae 	Base damage formula:Damage = \lfloor 500 * f(Intelligence_{DMG}) * f(Determination) \rfloor * f(Magic Damage) \rfloor * Hidden Trait \rfloor * Trait \rfloorWhere Trait can be 1.1 with Maim and Mend or 1.3 with Maim and Mend II. The exact value of the hidden trait reduction is yet unknown as of Endwalker, but a reduction of 10-20% is present.
==Use==
Despite Summon Titan's 25-yalm range, Rock Buster has only a 3-yalm melee range, while Titan-Egi is summoned at the summoner's side. As such, Titan-Egi will move within range of the target before executing, resulting in a slight delay before the damage is dealt. As Titan-Egi isn't dismissed until Rock Buster is executed, this can inhibit the summoner's ability to use normal Carbuncle-dependent actions such as or other summons. The summoner can aleviate this by moving themselves within melee range before casting Summon Titan, causing Titan-Egi to appear within range to use Rock Buster.
