the group will rush in pushing him into the barrel behind him.
the shield will go down for about 5 seconds. as soon as the shield goes up, bird will have to blast shot the shield off.

-mages keep the bird alive

This fight will last no more than 1 minute if done right. the shield debuff lasts about the same time as Blast Shot cool down, so the bird has to be patient and time his shot.
