I agree with 'the ironfoot', this setup gives you good armour save, good ward save and still a bucket load of attacks once frenzy kicks in. I'm not sold on the maiming shield it seems expensive for just 1 more attack especially with the Glyph Necklace the same points cost.
As well as the one more attack though it gives a 5+ armour save. Not as good as the ward obviously but stacks with armour and scaly skin. 2+ AS and 8 attacks, or an extra 15 points for 1+ armour/5+ ward but 'only' 7 attacks. I'm actually thinking that sounds better since the carnosaur will also be responsible for several kills a turn.
Hopefully not resurecting too old a thread but was reading through the army book again last night and came up with this idea; Oldblood; -Sword of Battle -Maiming Shield -Glyph Necklace -Bane Head or Curse Charm of Tepok -Light Armour -Carnosaur So still 7 attacks (8 with frenzy) a 2+ Armour Save, 5+ Ward save and the choice to take Bane-head or the Curse Charm as a magic item! What do you think?
I've run my OB/Carn with the bane head if I knew I was planning on taking on a tough character/general such as VC, Dwarves, Chaos. It works very nicely and is great at character killing. As for Curse Charm, I've not run it before but I can see it's definate advantage.
i usually run my carno with SoSR and malming shield, but after the last match i had with him, i need a ward save. that killing blow is just tragic.
