Tamurkhan's best and worst chieftain

[Peskyfletch]

Including units and abilities?
So far I'm finding Ezar best, as having a regiment of good missile troops to complement my troops, and the fimir one least impressive.

The Fimir is good for the replenishment bonus he gives to the army + lore of shadow spells are good to delete the strong armoured enemies and ranged units you faced, be it kislev or other chaos.
In fact i would recommand him as second chieftain after Krazyk

But at the best i would say the legendary hero Krazyk on his rot knight is an absolute beast in melee, and rot knights animations are so good he kills any single entitie without breaking a sweat.

And for the worst either the wolfkin or beastman.
The wolfkin doesn't provide anything better than an exalted hero of nurgle
While the beastman and his lore of beast is meh... Thought he allows you to summon 2 cygors in the same time on the field wich is fun

Also it seems that the wolfkin and beastman unique skill nodes have good synergy

I second it's hard to write off a Shadow mage that's a very useful spell type with good range and armor penetration he was my first pick-up to get a mage.

If you include units it makes them all better wolfman maybe less so but Mammoths are workable and he's fast as a mount and good 1v1 he's basically an assassin though I know that's a low priority for most people.

Dreadquake mortar gives it to the Chaos Dwarf for me and he's pretty slick himself.

Honestly I find Krazyk surprising in how good he is. He does nothing special except charge. But with a few rot knights he does that so good.

Yeah, I must say I wasn't really thinking of the sheer killyness of the fimirs shadow magic( even though,due to weird landscape features, I got seven hundred odd kills with him in one battle). I might need to re-evaluate. Maybe the khorne dude,although aspiring champions are possibly my fave unit and he himself is a monstrosity.
