1Round 1
At this point in the game, Coulder is not an offensive tool. Use it like you would normal Iceblock, except you can play more aggressive and then roll back to safety. You can still use it for booping/Pushing but it does no damage until round 3.

This is where we can pivot to Coulder being a legitimate offensive option. From now on, Ice wall is generally used as a defensive option to help survive until you get Coulder back.

Now that you have two walls, you can use first wall to drop behind target, roll them into it, and then use second wall for survivability to get Coulder back.
