He boosts a wild-hunt unit by 1.
This should trigger thrive.
I encountered a few times, when I correcly placed a wild hunt unit to the left of thrive unit, and thrive didn't trigger.
It triggered occassionaly when the thrive unit's power was on par with the base power of the deployed wild hunt unit.
Short explanation: The deployed wild hunt unit was boosted on deploy, also when placed correctly to the left of unit with thrive, the thrive wasn't triggered, despite the deployed wildhunt unit's power, post deploy, was greater than the power of the unit with thrive.
