Now I have to resort to cheat codes (/killall) so that I can get a fair fight.

No...

There are a plethora of videos on youtube on how to take down bonemass in multiple ways.

Many of those ways would make the spawn of an abomination also a non issue too.

Just one example is raising the ground near bonemass's spawn standing atop the high pillar of ground and sledge hammering til dead. This also would of course damage any abomination in the vicinity to the point of eventually killing it too.

All in all this is just something you have to learn to sort. Its doable.
