Iron Maiden
[Passive] Takes magic attacks in the place of adjacent friendly units.
[Active] Increases Guard range to 2 blocks. Reduces MDamage taken by 20%. Grants the [Iron Maiden] effect: Grants 0.8x MDEF as DEF, and after battle, deals hero's MDEF x2.5 as fixed damage to the enemy. Lasts 2 turns.
Information obtained by looking in the ConfigDataSkillInfo.json. It's essentially a "magic version" of [Lance Phalanx], taking incoming magic attacks and dealing MDEF fixed damage.
Now I wonder if [Lance Phalanx] and [Iron Maiden] can stack with its effects. Throw in Barb and Sorrowful Choice and it's Fixed Damage City. SirMarcusCalibur (talk) 19:53, 16 March 2019 (UTC)
Apparently Iron Maiden replaces DEF with MDEF, instead of adding it as I originally thought. Makes sense in hindsight, but the replacement ruins the skill itself. SirMarcusCalibur (talk) 06:19, 21 March 2019 (UTC)
