Wyverns

More likely, they just got overwhelmed. In my opinion, it's a questionable unit. It can be useful, but not very often. What I dislike most about them is their weakness. 105 HP for a level 6 unit is extremely low. If the enemy is casting spells, shooting, or hiding in invisibility, and the paladins are dealing massive damage, then the wyverns can only poison them. And even that isn't very effective. They're only slightly more effective than the assassins' poison, when comparing the damage increases, but assassins can shoot! However, under the command of Shack, they will look more impressive, and you can start considering choosing them.
