Besides leveling there is one more feature for heroes' upgrade - promotion. You can promote your heroes from one rank to another; ranks are displayed after the hero's name with number and color:
There are 12 ranks in the game:
- Green +1
- Blue +1
- Blue +2
- Purple +1
- Purple +2
- Purple +3
- Orange +1
You will need to collect a full set of gear to promote your hero. You can obtain gear in missions or in the shops. All items have level requirements.
Important: many items are combined from fragments (e.g. Giant Slayer) and other items (e.g. Dark Grail):
After promoting your hero all equipped items vanish. Their stats are added to hero's stats on vanishing so the heroes become stronger with each promotion.
Important: once an item is equipped, it can't be taken off and passed to another hero.
