'Poor utilization.'
The Hobgoblin King's abnormal talent was certainly impressive, but the way it arrogantly used it for show was just too stupid for Damian's comprehension.
Giving up the use of weapons just because your body could always be repaired? This was simply too wasteful!
If Damian had this absurd talent, he had many meaningful ways to use it. If the Bugbear was the one that awakened that talent in the end, it could have reproduced its sacrificial attack many times by resetting its bones over and over.
Bending the body beyond its limit and relying on the regeneration speed to fix the consequences was an overpowered combination. However…
'It's almost too dumb.'
Despite having enough willpower to resist the rage effect of both the Fate Limit and the Extinction Threat achievement, the Hobgoblin King was simply too inefficient.
