Draupnir rambles about Abbadon in Tacticus 

Abbadon is the warmaster of chaos he should have at least the same buff as a chapter master of the ultramarnes

That's before tackling draknyen

Why did you leave out Aethana as a buffer?

I only invested in abadon to get a bit easier time in Fall of Cadia and even then I think it was a bit of a waste

He isn't bad in some niche situations. Like helping new chaos characters kill 50 mobs and do 15k damage, or killing your own Aethana on arenas. In my opinion, "let the galaxy burn" needs rework, Aba is alright.
