Damage Taken

= Round {Enemy ATK
   x (1 + Enemy ATK Buffs)
   x (Enemy Elemental Advantage + Elemental Buff)
   x (1 - [Ally DMG Cut + Ally Elemental RST])
   ÷ (Ally DEF(10) + [Soul Master Bonus DEF ÷ 10])
   ÷ (1 + Assist DEF + DEF Buff + Accessory DEF + Mastery Passive)
   x (1 + DMG Range)}
   x DMG Multiplier

Notes:

• DMG Range is a random integer between -5% and +5%.
• DMG Multiplier is used for abilities.

Burst Damage

   x {A + (Burst Multiplier + Burst DMG buffs) + Special Burst DMG up}
   + B (values based on A)

	A	B
Awaken	5,5x	3.000
SSR	4,5x	2.500
SR	3x	2.000
R	2x	1.500
★	+0,5x	-

Notes:

• Burst DMG is soft capped at 1.000.000 DMG, and its buff multiplier is hard capped at +500% multiplier. The former can be increased up to two million with Exceed weapons, abilities and accessories. Any point of damage that goes beyond the soft cap will be reduced by 90%
  • Characters like Uriel or Mithra can bypass the 500% cap by adding to the Special burst DMG up using their respective tokens.

   x  Element Advantage
   x (1 + Burst Streak Buffs)
