Wrath of Cluck has 11 weapons that you pick from level-up cards during a run. Most weapons level up to Lv5, and a weapon at its top level with its partner passive can evolve. This page lists every weapon, how to unlock it, each evolution recipe and the passives behind them.
How do weapons evolve?
A weapon evolves when two things are true in the same run. First, the base weapon is at its top level, Lv5. Second, you hold its partner passive at Lv1 or higher. Then an evolution card can appear in your level-up choices. Taking it replaces the base weapon: the evolution uses the base weapon's slot, and the two never fire side by side. The evolution keeps the branch you picked. Before that, each branching weapon splits in two: once a weapon is at Lv2 or higher and has not branched yet, its card opens into two branch cards. You pick one, and the weapon goes up one level on that branch. Every evolution has exactly one base weapon and one partner passive, and one passive can complete several evolutions. One exception: Bubble Catcher has a single level, no branches and no evolution. The table below shows every recipe.
