Defense Decay

Defense Decay is a mechanic in Terrene Odyssey that occurs during battle.

"Each time a Character blocks an attack from another Character, they suffer Defense Decay, and their DEF is reduced by 5 until the start of their next turn. Defense Decay can stack, but a Character's DEF value can never drop below zero. Only Battle Damage causes Defense Decay and never damage from other sources like Abilities, Items, and Commands."

Rulings

 * Defense Decay is removed at the beginning of the suffering Character's turn. In a 2v2, a Character must survive all 3 other players' turns before getting to remove Defense Decay.
 * Damage from Retaliate is considered Battle Damage, and thus applies Defense Decay.
