Trivia

• Instant-Kill is not a debuff. Servants and Enemies have a separate Death Resist stat from Debuff Resist. Effects that prevent debuffs do not prevent Instant-Kill.
• Servants and enemies can be defeated from Burn reducing HP to 0.
• As of London update, Curse is now stackable.
• As of Shimosa update, Burn & Poison is now stackable.
• Max HP buff also heals unit.
  • Healing received from Max HP buff cannot be reduced by Heal Down debuff, but the buff itself can be prevented.
  • Normal healing cannot be prevented, but can be reduced by Heal Down debuff.
• Invincibility, Evasion, and Guts cannot stack.
  • Effect from Necromancy CE counted as permanent Guts and cannot be stack.
  • The third skill's Guts of Angra Mainyu is the only Guts that can stack with other Guts.
• Taunt can cause an enemy Servant's Noble Phantasm to fail to execute, but still use up a full Charge Gauge.
  • Needs confirmation! Sometimes behaves this way and sometimes does not.
