Guaranteed KO Resistance

Guaranteed KO Resistance (often referred to as Guaranteed Angel Idol, Angel Idol, or simply AI for short) is a buff that grants the target a guaranteed chance of surviving an attack that would otherwise kill them, leaving them with 1 HP.

KO Resistance Negation can ignore Angel Idol buffs, killing the target.

Stacking
KO Resistance effects from different sources can stack. This includes:
 * Spheres
 * Elgif
 * Leader Skill
 * Extra Skill
 * SP Enhancements
 * Brave Burst

The priority order in which Angel Idol effect from different sources is used in the order of Elgif, Sphere, Extra Skill, SP option, Leader Skill, and Brave Burst.

Interactions with Turn's End Damage
Damage from Additional Damage (DoT) and Poison that would otherwise bring a unit with a Guaranteed KO Resistance buff active to 0 HP will cause KO resistance to take effect.

Interactions with Damage Counter
Due to Damage Counter being unable to bring units to 0 HP, KO resistance does not take effect when a unit affected by Damage Counter is brought to 1 HP.
