warband 1
nine easterling warriors
black dragons
shields
pikes
banner
khamul
240pts

war band 2
six easterling warriors
bows 6pts
easterling captain
bow
98points

warband 3
nine easterling warriors
black dragons
shields
pikes
easterling war priest
155pts

the plan is to have warband 1 and 3 to charge in line formation while
warband 2 fires into enemy ranks
while the war priest supports khamul

In future perhaps list your army like this, as it is easier to understand what your using:

Warband 1:
Khamul (hero first)
9 easterlings with bows
3 with shield

Besides that, the list looks rather solid i suppose, you seem to have decent enough numbers etc.

Khamul is more effective if mounted, and if on a fell beast he can keep his will pretty high. But a horse for him is almost essential because he's not the best spell caster.
