Expert Tips
- Let's Bounce! (R) bounces enemies multiple times and roots on the final bounce. Use it in melee range for all 4 bounces.
- Cell Division (passive) re-forms from up to 4 blobs. Never die without at least 2 blobs nearby.
- Elastic Slingshot (E) gains range by pulling from terrain. Always initiate from a wall or terrain feature.
