Primarily a tank type, Amistr sports the highest VIT and Max HP growth among the homunculi. Its skills are all centered to serve as a distraction and take on hits for its master by switching their positions using Castling and by boosting its HP and DEF further. However, it lacks MDEF, making it vulnerable to magic, as well as offensive skills to quickly dispatch its target. Fortunately, its high enough VIT allows extremely high healing values from Potion Pitcher and Slim Potion Pitcher, saving a good amount of potions to heal it to full health.
There are only 2 species of Amistr. Transforming Amistr from its adolescent appearance into a mature form requires a Stone of Sage when it possesses loyal disposition towards its creator.
