Item bans and shop locks

Banning removes an item from the shop and crate pool for the rest of the run. The ban system unlocks when you win a run on Danger 3 or higher, and you switch it on or off in Run Options. Each run starts with 8 ban tokens. Since the 12 November patch you also gain 1 token every 4 waves, up to wave 20.

Token counter

The crate screen shows tokens as used/total. Before 12 November that counter could go negative after extra tokens were added; the patch fixed it.

What to ban

A ban is worth a token when it removes an item that keeps appearing and that your build will never buy, which raises the chance of everything else in the pool. Characters already have built-in restrictions: Droid never sees a long list of healing and regeneration items, the Wounded never sees Max HP, regeneration, Life Steal or Armor items, and the Arsonist never sees Melee or Ranged Damage items. Do not spend tokens on items your character cannot be offered.

Since the New Dawn update, Piggy Bank and Crown leave the item pool after wave 20; the 12 November patch fixed them returning in Endless.

Locking shop items

Locking is separate from banning and has no token cost. A locked item stays in the shop when you reroll and carries over to the next shop, which lets you buy it after the next wave. Controller and keyboard shortcuts exist for locking, banning and rerolling.

Bans versus Item Sets

Bans remove single items for one run. Item Sets remove a whole DLC or update for every run until you switch them back.
