Check out this customised monster slayer...
Saurus Old Blood
Great Weapon
light armour
the maiming shield
venom of the firefly frog
glyph necklace
blessed spawning of sotek
blessed spawning of quetzl
blessed spawning of itzl
that's
6 poisoned attacks of Ws 6, strength 7 (if using great weapon) on the charge.
Or
7 poisoned attacks of Ws 6 strength 5 (if using hand weapon and maiming shield) on the charge
Also, an armour save of 3+, ward save of 5+ and toughness of 5.
And that lot doesn't include the carnosaur who has 4 attacks of Ws 3 strength 6 and causes D3 wounds on large targets !!!
This guy even stands a chance (a smallish one) against Grimgor Ironhide, providing he survives Grimgor's 1st strike.
However, I wouldn't advise fighting Grimgor with this Old Blood. You're better off using this saurus to tackle lesser foes like Dragons and Greater Demons :)
