Glacier's Toolkit is an active item in Glacier's Laboratory, a mod for The Binding of Isaac.

Spawns a permanent and unique stick familiar, if Isaac doesn't have any.

The stick can be swung in the direction Isaac is shooting. It knock pickups around, has a 35% chance to deflect projectiles, deals 3 + CurrentStage x 2 damage to enemies and confuse them for 1.5 seconds.

If Isaac already has the stick, using it causes Isaac to hold it above his head and opens a blueprint.

While the blueprint is opened, Isaac can choose a temporary part and install it onto the stick by pressing respective fire button, at the cost of keys. He can also use blueprint to install another one, or remove current one.
