Craglorn Anka-Ra worldboss soloable?

mocap

Trying to protect that priest and nothing. He die to fast. Other bosses are easy - faceroll Anomalys with Puncturing Sweep, Troll is not so hard as well, just more ranged attacks. Don't know what to do with Anka-Ra boss. Breath of Life doesn't heal the priest, no physical obstacles i could create. Maybe grab Inner Rage and insta aggro all that bloody archers?

Anyone who soloed this bosses, give me advice pls )
