I chose for Haka to Crush the Abject Refugees in the Dok'Thorath Capitol, placing them under Savage Mana so that he could deal damage to Shu.
Sorry about your plight, refugees!
Know that your destruction serves the greater good by having Haka chew you up and spit you back out on the enemy.
The heroes will tend to your needs next time, I promise.
I'm curious now, what IS happening, story-wise, when Haka uses Savage Mana to collect targets?
