Magic Shield - 5

Cutscenes
The birds have defeated all of the mage pigs. At first, it appeared that the shield was still holding strong, causing Wizpig to laugh at them. Suddenly, the shield was deactivated, shocking and angering Wizpig. He then flew into his castle with both the final egg and King Pig's crown.

Enemies
If Spirit Caller manages to fully charge his Call Undead skill, then one of the following enemies could be summoned:

Strategy
Choose Red in Paladin, Matilda in Druid and The Blues in Tricksters. First, attack with Red and The Blues. Heal the birds with Matilda if the birds' health is not full and if it's full, attack with her. Use The Blues' secondary skill on the bird which has been spelled by Spirit Caller's Mass Leech power so he'll not heal anything. When the Rage Chili is full, give it to Red to deal strong damage on Spirit Caller, or give it to Matilda when the birds' health is too low or when Spirit Caller has less health than the undead. Repeat this over until you win or lose, but when Spirit Caller is dead, quickly fill the Rage Chili by the damage so you can give it to Bomb and explode all of the undead.
