Disclaimer
All information in this guide is based on the JP and CN version of the Ryza collab event. Some details may be different for the Global version of the event. Any discrepancies will be corrected as soon as possible.
Event format
The second part of the event will still have you farm event stages, but for a different event currency. The event currency that you get in this part of the event comes in the form of boss challenge tickets. These tickets can then be used to challenge the event boss in order to obtain red crystals. These crystals will be used for the alchemy pot, a box gacha style reward system consisting of 7 boxes. More details on the alchemy pot can be found in the Alchemy Pot guide.


Event Boss
There are four difficulty stages for the event boss; Normal, Hard, Advanced, and EX. The more difficult stage will reward more red crystals for the alchemy pot. However, they are also more challenging and require more challenge tickets as well.
Note that the EX difficulty can only be challenged once per day.
Boss Difficulty | Challenge Ticket Cost | Red Crystals Reward |
---|---|---|
Normal | 10 | 6 |
Hard | 20 | 15 |
Advanced | 30 | 30 |
EX | 30 | 150 |

The Event Boss is a Red Attribute Boss and is accompanied by 2 Green Mobs.
After the boss’ 2nd turn, she will begin to build up a passive stack. She will gain 1 stack after every turn (ally or enemy) up to 5 stacks. If she has 5 stacks at the start of her turn, she will transform into her 2nd phase. You can see how many of this passive stack she currently has by looking at the blue icon underneath her HP bar. When she transforms, she will regain 70% of her max HP, remove all debuffs from herself, and gain a shield. Defeating her in this form will win you the battle.
Note that she cannot be killed before she transforms into her second phase as the boss will always heal back to 1% HP.

Event Boss teams

Event Boss tips
- If you are having trouble surviving the boss’ AoE attacks, be sure to set the Guardian Robot as your support.
- is possible to cheese the boss with a Roco poison comp. However, it is extremely RNG dependent as it is reliant on Roco not deflecting off of the boss. Use only as a last resort.
