by BrokenBuilds Wiki

Thief carries the largest single SPD modifier in the game at +4. A 7 base SPD kitten lands at 11 effective SPD, which is enough to flank across the entire field in a single action. The class pays for that speed with -1 STR and -1 CON, so the playstyle is built around hitting from positions where the enemy cannot retaliate. Backstabs, stealth, and item theft all reward attacks from behind the enemy line. Luck gets a +1 bump on top, which stacks with crit-boosting items to turn the build into a priority-target deletion tool. Pair with a Tank that holds aggro and a Psychic or Mage that shoves priority targets into the Thief's strike range.

How to Breed

  1. Pair the right parents

    Father
    high LCK cat with crit-on-hit passives or an item-steal ability
    Mother
    high SPD cat with Backstab, Sneak, or any stealth ability
  2. Set up the room

    Comfort4
    Stimulation50+

    Keep this line as far from inbred as you can. In 1.1 inbred kittens inherit parent birth defects at a much higher rate and get less benefit from Stimulation, and a defect on a fragile glass cannon ends the run. Push Stimulation high, since it now lowers defect inheritance rather than raising it. Pair cats from separate lineages rather than breeding cousins together.

Notes

1.1 gave Thief small movement and damage bumps. Caltrops gained a movement point (five on the upgrade), Poison Gas gained a poison stack, and Nail Flurry+ now locks its hit count at cast time so DEX swings no longer undercut the rotation mid-ability. The job still overlaps with Hunter, and after Hunter's own 1.1 changes the two are closer than before, but Hunter still does the long-range finisher job more reliably; Thief earns its slot on item theft for specific runs. A bred Thief with 7 SPD and 7 LCK sits at 11 effective SPD and drives base crit toward 14% before any items. The class is fragile by design, so the build avoids damage through positioning instead of soaking it.
