Been fiddling around the game on the weekends and here some patterns.
- Rewarding and incentivicing, there are occurrence of better reward structure if dont spend your gems. Chests does have a chance of getting armor as well.
- Achieving of S Rank is not difficult for PvE and every mission on record time gives you a free gem.
- Event quest is easily achievable in teams, higher HR rank and equipments is better.
- Upgrading of Equip/Pattern: Need to farm for requirements in both PvE missions, material/gold event quests. Its quite easy to upgrade for the first 20 levels, beyond that it is largely dependent on monster drops at later PvE dungeon instances.
