QUOTE(Tutorial: Spells. Getting Computers to Use)
- Dark Swarm -
*A nearby defiler will put up a darkswarm when some of its melee units are being attacked by any ground unit with range
*The defiler won't always use it though, additional units in combat will encourage it to use its dark swarm more
*They will use this to help protect allies too
*Only seem to want to use it once, using a melee AI will make them use it multiple times
That's all I know.
