Magic Flower can increase the healing from 1 HP to 2 HP, however it will still only raise your Max HP by 1. For example, if the Ironclad ended the combat with 70/80 HP, Face of Cleric and Magic Flower will make him have 72/81 HP (ignoring other healing relics).
Trivia[]
In future battles, the face of the character will stay the same despite this event happening.
