Rocket Launcher gives him some rocket-jumping capabilities, Force Field allows him to close off movement options, Cheat Death lets him turn bad fights around, and a Pulse released in the middle of a teamfight can dictate the outcome.
—

Launch a rocket that deals damage in an area and applies knockback.
Rutger receives 50% damage and 175% knockback from his own rocket if he's in its impact radius.

Create a field at target location that pushes enemies away from its outer edge.

When taking otherwise fatal damage, Rutger becomes unkillable for 4s.

Release a fast pulse in a large area that damages, slows, and prevents enemies from using abilities.
The damage dealt is based on how close the enemy is to the center of the pulse.
