Notes |
| New Horizons (Beginner) |
40 |
Guaranteed 6★, complete all 40 pulls |
| Standard |
80 |
No rate-up, 300 pulls = selectable 6★ |
| Featured/Limited |
80 |
Rate-up character, 120 = hard guarantee |
Pity System Rules
| Rule |
Details |
| Soft pity |
65+ pulls increase 6★ rate by 5% per pull |
| Hard pity |
80 pulls = guaranteed 6★ |
| 50/50 |
50% featured, 50% standard pool |
| 120 guarantee |
Lost 50/50? Next featured guaranteed (only THAT banner) |
| Pity carryover |
Pull count carries, 120 guarantee does NOT |
F2P Pull Strategy
- Complete New Horizons first (40 pulls = 6★ + weapon selector)
- Save for limited banners (need 120 for guarantee)
- Don't pull without 120 ready on limited banners
- Standard banner is low priority
