I'm running into more DM enforcers that become unkillable if I don't have a 2nd grenade to throw.

I'm also running into bugs that take damage down to zero health, and continue to attack for minutes afterward taking no further damage.

I can't kill a monarch with zero health that is attacking me, even when I lob a grenade under him.

Specifically ran into this a few times at the Kinship hellbug siege.
