If there is no Elven unit or building within about a screen width of the Converted unit it will go back to it's old side. Renewal - This resurrects any dead friendly unit to an Apprentice. He possesses a medium strength melee attack. This Elf is in tune with the natural world and as such can summon many creatures to aid him. He has a weak ranged spell attack.
Heroes only suffer damage.
Command - Causes a critter to come under the control of the player. The critter has an attack based on its species, but also a vision range. For example, birds have crappy attacks but make great scouts, boars have better attack but horrible sight range. The Lightning Gryphons are enchanted Gryphons with powerful magical abilities. He can fly or walk but flying requires a continual mana burn.
