- Instant Death is not a debuff. Servants and Enemies have a separate Death Resist stat from Debuff Resist. Effects that prevent debuffs do not prevent instant death.
- 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 blocked.
- Normal healing cannot be blocked, but can be reduced by Heal Down debuff.
- Invincible, Evasion, and Guts cannot stack.
- Effect from Necromancy CE counted as permanent 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.
