Bowling Bash is a complex, non-deterministic, and recursive skill. This complexity is enhanced further by "gutter zones", which introduce a position dependent divergent behavior tree. Gutter zones start every 40 cells and extend up to 5 cells north and east.

The initial application of Bowling Bash applies knockback to the enemy parallel to user's last successful movement. Therefore, it is possible for Bowling Bash to knock the enemy towards, away, or tangent to the user. Bowling Bash behavior then diverges dependent on whether the user is within a gutter zone.

If the user is within a gutter zone, the enemy is knocked back one cell for every two skill levels then receives physical damage.

If the user is not within a gutter zone, the enemy is knocked back one cell and detects enemies within a 3x3 square AoE. All enemies that have not been previously detected (including itself) receive physical damage. Other enemies are knocked back 1 cell in a random direction and initiate the recursion anew, detecting enemies within a 3x3 square AoE.

This recursion continues for each enemy tree until a termination condition is met. These conditions include:

• The enemy knockback is prevented by terrain
• The enemy encounters a gutter zone of an incrementing position value
• The recursion counter exceeds the recursion limit (scales with skill level)

It is noteworthy that the gutter zone propagation limitation is only applied to incrementing position values, i.e. north or east, and is not applied to gutter zone transitions of decrementing positional values, i.e. south or west. As an enemy may only be detected once, enemies may receive at most two damage waves per cast regardless of how many recursive AoEs they are included in.
