A nice little combo I spotted yesterday in my army book is the peral of infinite bleakness; this item makes the character and the unit immune to psycholgy for only 25 points.
Also the champion in a cold one unit can take 1 magic item up to 25 points. Combine these two and the unit is immune to the annoying stupidity tests which are always failed at the worst time.
I havn't seen this litle number on any forums yet so i am just throwing it out there.
Also what are your thoughts on the hydra banner ( +1 attack on the first round, incl mounts) stacking with the cauldren of bloods +1 attack. This is a combo I thought up for a unit of cold one knights but i am not sure if it will stack. I know that two cauldrens don't stack attacks.
Any thoughts would be appreciated.
