Joyeuse : 35D 224 Delay
Delay with 35% haste = 146
Attack Rounds in 30 mins = 740
Swings in 30 mins = 1110
Enspell I Dmg = 1110 x 20 = 22200
Enspells II go from 18 - 36 at the rate of +1 DMG per hit. So It takes 18 Hits (18, 19, 20...35) the average of this is 26.5. This happens every time you recast Enspell II. With 'Composure' up, An Enspell II (assuming same duration as enspell I) lasts 7min 30s.. So 4 casts in 30 mins (3 if you end exactly at 30 mins). So 18 x 4 hits at 26.5 dmg Enspell II.. the rest of the hits at 36
Enspell II Dmg = 72 x 26.5 + 668 x 36 = 1908 + 24048 = 25956
