Boss Batles typically occur every 5 quest levels. It will typically award Coins, a Trap, and either a Power Potion or a Energy Drink.
These battles are fought with your main Cryptid. You can also choose two other cryptids from your friend lists. Boss Battles eventually get so hard that this is not possible to without your two friends cryptids. You can use power potions during the Boss Battles to replenish your defence.
The battle happens in 2 stages:
- Stage 1 you and your friends Cryptids attack the boss.
- Stage 2 the Boss attacks you and your friends Cryptids.
- The Key is to get him down to 0 health and win.
Occasionally their is a hidden reward after defeating a boss or a event boss and you get a free rare card.
