Final answer:
Thrill of the Hunt in Tiers 1 and 2 heals units for 400/700 Health upon a kill, with the 2/2/22 update increasing this from 300/600, and the 1/20/22 update removing Thrill of the Hunt III.
Step-by-step explanation:
The healing effect of Thrill of the Hunt at Tiers 1 and 2 is that your units heal 400/700 Health on kill, respectively. In the update that occurred on 2/2/22, there was a change in the Heal on Kill values from 300/600 to 400/700. Another update on 1/20/22 resulted in the removal of Thrill of the Hunt III. Hence, the correct answer to the student's question is 'Your units heal 400/700 Health on kill. Thrill of the Hunt III has been removed.'
