Experimental Hammer

It grants one random compatible Hammer immediately for ten encounters.

Use it when

Use it early when the weapon benefits from almost any compatible Hammer and ten encounters cover the needed route segment.

Limit

The Hammer is random and disappears when the encounter timer ends.

If it is absent

Use a god keepsake when a predictable boon matters more than a temporary weapon upgrade.

When to replace it

At the next keepsake cabinet, replace it after its timer or room duration expires.
