7th Ed. To slay a Tyrant

[Aparach]

I play 2250 ogres all the time and bring 3 butchers. This is how I defend against magic heavy armies for the 2 turns it takes to get me into combat.(in my allcomer's list)

My tyrant is in a unit of 4 bulls full command and a look out gnoblar. Also in that unit is a butcher with grut's sickle and a thiefstone. Now my tyrant has MR1. My other butchers have bangstick/scroll and hellheart as their items.

Turn 1 I hellheart to help stop magic. Especially effective against slanns who are always using 3-4 dice per cast. Turn 2 hopefully I still have my scroll, if not 5 dice and MR1 on my tyrant will keep him alive. I know what spells you have, I won't leave you with enough dice to cast pit of shades without me having a chance of dispelling it.
Turn 3 I'm in combat. And that only cost me 90 points. On the flip side, I got 8 powerdice and a bound spell and grut's sickle vs your 6 dispel dice. I'll be getting of just as many spells. Maybe even MR2/regen on my tyrant in turn 1.

So no, don't expect to magic a tyrant to death.

As far as a unit of kroxigors hitting my tyrant. Here's the math. 6 attacks, 3 hit, 2.5 wound, 1.67 get past wyrdstone necklace. We'll call it 2 wounds. He has 3 left. He has 5 attacks, 3.333 hit, 2.77 wound after tenderizer does D3 wounds that's 5.55 wounds. Possibly 2 dead kroxigors.

I was using my basic setup of heavyarmor, tenderizer, greedyfist, wyrdstone necklace for the tyrant.

You need combat res to beat him and lizardmen just don't have enough.

Brilliant analysis! Never played Ogre Kingdom, but I can see that a tyrant is quit a match in CC..
I suggest a rain of fire from both shooting and magic. Don't bother going for heavy spells like pit of shades.
Remember, you uses a lot of dices on a spell that most likely dont do a damn thing..
I would go for lots of magic missiles and maybe death lore for steal soul to slowly pick him apart. Then I would take 3-4 units of 10 skinks each with blowpipe and some sallys. Finaly I would go defensive a try to get a combined charge on that tyrant, maybe from some swarms(to hold him-and possibly do a wound) and a heavy hitter like kroxs or a scar-vet.
