Moral

[KNK]

How do you make moral of all units in the game go to +3 ?
Humans is simple,griffin+griffin portrait+army drum or picture of a knight or marshall baton
Lizardman,scaly braclet +2 and tirex +1
Undead,set of death + death knight,im not sure though about this
For some neutrals it is voice of the dragoin from the mind skill tree,but not al of neutral are animals,what about moral of trolls,cyclops,evil beholder,assasin,etc.
But what about dwarfs,demons,elfs and orcs ?
I know about heroscreen,it's a great tool but not perfect.
