New unit, it can vomit lava on the ground. Bit of a hassle with the sprite having only two directions it can face, at first I thought I would just make it so that for every target position it wants to attack, there can only be two valid attacking positions, left and right of it. Seems like it could be annoying when playing, though, so instead of this, they 'take into account' that their lava pool will grow a few tiles big, and simple 'attack' from any adjacent tile. If that doesn’t happen to be left/right, the pool will simply take a bit longer to reach the target enemy.
