Effect: You summon a Medium magma beast in an unoccupied space within range. The magma beast has a speed 4 (8 while charging) and resist 5 fire. You can give the magma beast the following special command.
Standard Action: Melee 1; targets one creature; Intelligence vs. Reflex; 1d10 + Intelligence modifier fire damage, and the target takes ongoing 5 fire damage and is slowed (save ends both).
Intrinsic Nature: If you haven't given the magma beast any commands by the end of your turn, it attacks an adjacent creature or charges the nearest creature it can charge and makes its listed attack (above) in place of a melee basic attack. Otherwise, it moves its speed toward the nearest enemy. In addition, you are slowed until the end of your next turn.
Symbiosis: While the summoned magma beast is present, you can shift 2 squares as a move action. Each creature that you hit with a basic or at-will attack cannot shift until the end of its next turn.
