Slime Summoning Expansion Update

Summoning expanded to level 15

The maximum Slime Summoning level increases from 10 to 15. Levels 11–15 retain level 10’s C-grade 100% chance. At levels 11–15, each summoned slime costs 1b gold and grants 1 XP. Results appear at 0.1-second intervals.

Slimes per summon / total cost

  • Lv.11: 2 / 2b
  • Lv.12: 3 / 3b
  • Lv.13: 4 / 4b
  • Lv.14: 5 / 5b
  • Lv.15: 7 / 7b

XP needed for the next level

  • Lv.8 → 9: 1,200
  • Lv.9 → 10: 2,000
  • Lv.10 → 11: 2,500
  • Lv.11 → 12: 3,000
  • Lv.12 → 13: 3,500
  • Lv.13 → 14: 4,000
  • Lv.14 → 15: 4,500

Requirements for levels 8 and 9 have been reduced. Your accumulated summon count is retained and used with the new level thresholds. Level 15 is the maximum.

Auto Merge improvements

Auto Merge now determines the whole batch before showing the results. Merges that require a success roll proceed more smoothly. Failure bonuses still apply separately to each grade and reset on a successful merge of that grade.

Larva gold increases

Base gold from normal larvae increases by 3 at each 100-stage milestone: stages 100–199 give 203, stages 200–299 give 206, and stages 300–399 give 209. Boss rewards remain 10 times the normal amount.

Other improvements

Summoning tooltips now show the maximum number of slimes summoned. Summoning-level achievement thresholds have been aligned with the current level requirements.
