I got him yesterday on my first try despite having started the fight early due to bad positioning during the Trife encounter. It just took approximately forever.
Party setup: Knight / Witch / Enchanter / Wizard. The Dragon got to act exactly once, at the very beginning of the fight. After that he didn't do anything anymore.
Enchanter and Wizard both dropped an Elemental (ice and earth) into the middle of the two-packs of summons as a distraction, Witch cast Drain Willpower on the boss and pelts him with Piercing Ice Shard, freezing him. The summons waste their turn on the two elementals, Knight closes in to the Dragon and gives him one.
In the second round (once Glass Cannon kicked in) the two wizards recast their elementals next to the dragon, while the wizard and the witch cast Boulder Bash on one of the packs each. The witch then recasts Drain Willpower and Piercing Ice shard to keep the dragon frozen, Knight and Elementals attack.
After that it just came down to keeping the Dragon frozen throughout the whole fight and dumping another Boulder Bash on the Summons as soon as one of them got up. When neither needed to be done the casters fired their single target non-fire spells at the boss or beefed up the Knight until the Dragon finally succumbed after about six or seven rounds. Astarte was never in any kind of danger.
Crowd Control is king in this fight.
