[SPOILER=" "]Welp, let me do it out on with the formula.
PRE
Special Upgrades * Magic Damage * (Elemental Mastery + Elemental Mastery Title + Prefix Title + Magic Attack Enchants + Intelligence Related MATK) * Magic Mastery Modifier * (Base Damage + Reforge)
(1 + 0.17) * (1 + 0.29) * (1 + 0.15 + 0.1 + 0.08 + 0.1 + 1500/2000 ) * 1.1 * 340 = 1287 (one charge)
POST
(Base Damage + (MATK from special upgrades, titles, staff upgrades, MATK reforge, and MATK enchants, intelligence) * Ice Spear Modofier) * Ice Mastery + Ice Mastery title
(240 + ((68 + 32 + 29 + 80 + 10 + 300) * 1.4)) * 1.25
= (240 + (519 * 1.4)) * 1.25
= 1208
Keep in mind this is not total endgame, there is no rosemary gloves nor ice mastery reforge which would side it more towards post.[/SPOILER]
[SPOILER="Pre-Zero"]Constants: (Total ~340)
240 (r1 Ice Spear)

This is how it should work.
