AS you can see from above he took out 7 (including 3 MC's) units on fine with only 5 body guards.
Of the seven units Kharn and his buddies took care of, the first unit charged them in cover.
They then charge a mawloc, something that should be expected to die when charged by a dedicated close combat unit like that. Yeah it has a lot of wounds, but low attacks, low weapon skill, and moderate initiative do not mean it can take the likes of them on, not when they are led by a unit champion or Kharn.
The gaunts are little more than a speedbump, the tervigon (low the mawloc) has no right assaulting that unit.
Of all seven units that got charged or charged, only the hive tyrant had any chance to decimate those six models and it either sounds like some bad rolling came your way, or your friend pulled a big one over on you.
Speaking of which:
Also, i think my buddy might have fucked me over a little with the rules as well. Like he didn't tell me that he had to auto challenge my tyrant
Its the champion of chaos rule that their unit champions and leaders all have. Where other characters and leaders have the option of picking and choosing those fights, chaos do not; and sometimes this can lead to a bad situation for the chaos player.
Additionally, it seems like your friend may not have been playing the betrayer rule at all; either that or he had some very good rolls.
In each of those combats he should have been getting one or two 1's, whittling his own unit down until it was just him. Next time you go up against Kharn and a bodyguard keep an eye out for Kharn's 1's to hit; if he has been ignoring that rule and suddenly has to start playing it, you may be surprised how much less threatening Kharn and his unit suddenly become.
and when i assaulted him with my hormagauts when we both were in the forest he waited until i made the move to remind me that i was assaulting though cover and would go at I-1.
Thats rather bad form from your opponent, serving to make him out as a bit of a dick.
Also my Tyrant with L-W bone-sword didn't do any damage against him.
That has to be bad rolling, and any remaining gaunts that attacked Kharn did nothing as well?
How was your tyrant armed?
in two rounds of combat on two charges with my tyrant i rolled a total of 6 ones to wound lol.
Sounds like your tyrant should invest in old adversary. Hello re-rolling 1's.
