Stat Priority

  1. 1. LUK
  2. 2. AGI
  3. 3. STR

A tested split lands around 70 LUK, AGI pushed toward 90 and the rest into STR, aiming for 60-70 CRIT total from stats and cards. Some players instead prioritize STR at least equal to AGI, then LUK, or go full STR before AGI and LUK. Priorities vary here, so lean on the tested split above if you want a reliable target.

Tips

  • CRIT needs to come from cards as well as LUK — two Soldier Skeleton, two Baphomet Jr. and a Kobold card push it toward 80 total.
  • Katar has lower sustained ASPD than dual daggers but hits harder from a stealth burst opener, which is why it leans PvP.
  • Sonic Blow can crit in this version, which is what makes the CRIT-stacking stat and card picks worthwhile.
