I had a game vs Caspar, he had 3000 pnts of kroot heavy tau and I had csm with sonics and an ig allied mob.
He had occupied a trenchline and was damn near impossible to shift, which forced me to go in piecemeal. Basically I was getting shot to ickle wickle bits.
Around his biggy objective, he had a swarm of kroot, including dogs and ox, about 70 of the little blighters.
In reserve, I had 5 twin lighning claw termies ds, and a squadron of 2 hellhounds outflanking (creed).
They turned up on turn 4.
At the end of turn 6, there was 1 solitary kroot left.
Never seen anything like it.
