Void Spirits
150 kills / Savage Ring
Grants a short speed boost after slaying a monster, useful for chaining kills and moving through combat floors faster.
Bats
200 kills / Vampire Ring
Restores a little health when monsters are slain, adding sustain for long mine days and lower-food routes.
Skeletons
50 kills / Skeleton Mask
Unlocks the Skeleton Mask cosmetic reward and adds another completion marker to the Adventurer's Guild board.
Cave Insects
80 kills / Insect Head
Unlocks Insect Head, a novelty weapon that also marks early combat progression.
Duggies
30 kills / Hard Hat
Unlocks Hard Hat as a cosmetic reward and closes a quick low-count board target.

500 kills / Burglar's Ring
Raises monster loot chances, making coal, rare drops, combat books, and Skull Cavern resource loops more rewarding.

60 kills / Crabshell Ring
Adds defense while worn, a simple survivability layer before stronger boots, food, and Forge combinations take over.
Mummies
100 kills / Arcane Hat
Unlocks Arcane Hat as a Wizard-style cosmetic reward for Skull Cavern combat completion.
Pepper Rex
50 kills / Knight's Helmet
Unlocks Knight's Helmet and turns a rare-floor grind into a clear completion milestone.

Magma Sprites
150 kills / Marlon's Phone Number
Allows calling Marlon to use Item Recovery Service from home, reducing the friction after a bad combat loss.
