Old Hose

A common weapon from the Rubber set that fires a water jet down an entire line with Knockback 10, converting all tiles in its path to water and passing through obstacles. Deals no damage, but the enormous knockback and full-line terrain conversion make it excellent for disrupting enemy formations and curing Heatwave. Particularly strong in The Desert chapter, where converting tiles to water neutralizes heat hazards across a wide area.

Knockback 10 is extreme — any unit in the line is blasted to the end of the room, potentially slamming into walls for impact damage. Converting an entire line to water tiles simultaneously creates a wide water path that can extinguish fire columns, enable electric-element chain attacks, or allow Water Bottle refills across a broad area. The obstacle-piercing shot means it works even through terrain.

A utility powerhouse in The Desert where water creation is uniquely valuable. Also excellent at creating long water lanes for electric-element combo attacks, or as a knockback tool to launch multiple enemies simultaneously. Part of the Rubber set for builds collecting Rubber synergies. Surprisingly versatile despite dealing zero direct damage.
