Goblin Army with 9 chariots - 2K

The chariot unit rode over everything. Both the BSB and Grom's Chariot joined the unit, making the unit 2 ranks of 3, plus Grom on the flank of the unit's front (different base size). The +1 chariot rank made Grom LD8. When they charged they hit with: 4D3+4 S5 Impact Hits, 3 S10, I10, -3 AP attacks from BSB, 4 S5 -1 AP Killing Blow attacks from Grom, 9 S3 attacks from Wolves, and 12 S4 -1 AP spear attacks from Goblin chariot crew. They utterly destroyed anything they charged.

50 Goblins spears were also really good. Dishing out a lot of attack (18 spear attacks with boss, plus 6 Nasty Skulker attacks) with a static +5 Combat res (3 ranks, banner, Big Red Raggedy Banner). What's more, when they win combat, if they out number their enemy by more than 2 to 1 they cancel the "fall back in good order" result, which was key in every game (It's nearly just as powerful at the Fear rule from older editions in WFB).

I would drop the Snolting Pump Wagon and probably the skirmishing Goblins (to hard to control with Impetuous).

Also, although I have fun with my Shaman on chariot, in the future I'll keep him on foot or on a Giant Wolf. Idol of Mork is a great item - extends dispel range by 3" and once per turn you may re-roll a dispel roll. Must take item in my eyes.

Glowly Green Amulet also an excellent item, which virtually made my huge chariot unit immune to magic.

Big Red Raggedy Banner will probably be in every O&G list, it's really good.
