It is relatively easy when you are using the Water Element. Although it has a good mix of melee and range monsters it really shines in magic attacks.
It also has a lot of good tanks with high HP and Armor and if use the summoner Keyla that gives +1 in speed and armor synergizes well with a lot of the creatures.
That being said Water element also has Alric Stormbringer which gives +1 magic attack and so is also a good counter to the Water element.
Seeing the enemy use the Diemonshark as its primary tank and attacker I knew I would be able to win this match.
The pixies being boosted quickly dispatched the tank by round 2 and the Pelacor Bandit killed the Ice Pixie at the back immediately.
With 2 out of the 3 down immediately it was a breeze to finish the match.
