alright hear me out I already know how comedic my unit is. But I've been playing a bit of total war... what if I could have a skink chief and crew? How much would the point be? Hmmmmm
Just getting the Skink keyword would be pretty useful for the Dread. This means we could give it: Extra attacks with Steg Chief command ability +1 to hit with Skink Priest command ability +1 to save and run/shoot/charge with Skink Priest prayer Then consider that you wanted it to have a Chief on the howdah, presumably making it a Hero. This unlocks: Command traits - think Nimble for +1 save, or Prime Warbeast, giving it more extra attacks Artefacts - think Stegadon Helm for better save and damage, or Chamon artefact for ignoring the first point of rend. I reckon things start to snowball out of control pretty quickly. You could suddenly be dealing with a 37 wound, 2+ save destroyer of worlds with up to 6 bite attacks that each deal 6 damage (not even considering his claws and tail). For those reasons, I think the keywords alone would add around 150 points to his cost - and that's not considering any ranged attacks or hero attacks that a howdah with some Skinks and a Skink Chief might add.
I think id go Nimble with cloak of feathers for a flying 15" move 3+ save -1 to be hit 35 wound monstrosity... before abilities/prayers/etc but hey that's just me
