Keep completing quests and capturing runemals until you have 4 or more DIFFERENT runemals of level 5 or higher. Then go to the green flag on the map and win the battle.
Your chances of completing the quest are higher when :
- You have higher leveled Runemals
- You have 6 Runemals or more (so you can fill all spots)
- All your runemals have maximum health.
In battle:
- Obviously try to collect as many elements as possible, but also focus on getting some of each, so each of your runemals can perform an attack.
- If you for example have 4 opposing runemals in a round, focus your attacks on 2 runemals,to make sure these 2 are defeated. This will results in your runemals having to take less damage.
