- Tap Menu, then Inventory, and then the Reserve button at the bottom. Multiple weapons can be selected to be reserved in a vessel.
- Tap the Reserve button found on any weapon or summon details screen to reserve the weapon or the summon's EXP in a vessel.
- You can also automatically reserve the EXP of items obtained from quests to a vessel by enabling the auto-conversion feature. To enable it, go to Settings, tap Miscellaneous, go to Auto-Conversion Settings, and set the criteria.
- Weapons with skills need additional setup.
Notes:
- Bonus EXP won't be given for upgrading an item with another of the same weapon group or the same element when a lazuline or scarlet vessel is used.
- 9,999,999 lazuline and scarlet vessels can be held. No more EXP can be reserved past this limit.
- Journey Drop boosts or boosts from other campaigns will not take effect when reserving EXP in vessels, but they do take effect when the vessel is used.
- Plus mark bonuses will be automatically stocked when items with them are reserved.
- EXP from some weapons and summons can't be reserved.
- The EXP reserved does not scale with uncap levels. Uncapped items are sometimes better Reduced.
- Weapons with skills only grant one anvil point when reserved. Weapons that already have skill levels are better used for manual upgrades.
