Elves sometimes carry lembas wafers, dwarves carry cram rations, and orcs carry tripe rations.

If you’re wearing some orcish armor, some orcs may see you as another orc and be peaceful. Possibly the chance of this happening is higher for each piece of orcish armor you are wearing.

When you cause a Yendorian Army monster to flee, nearby lower-ranking monsters may also flee. Possibly extend this to other ‘pack animals’ such as orcs or ants.

Orcish Town, but it’s a relatively normal Minetown, just with all the gnomes and dwarves replaced by peaceful orcs.

Orcish characters will never be able to tame elves, and elvish characters will never be able to tame orcs.

Ideas about nerfing the player’s ability to scare off a large group of Yendorian Army troops at once:

• Non-fleeing troops grudge fleeing ones (they’re deserters).
• Troops are immune to fleeing (possibly only immune to fleeing triggered by low HP, and still capable of fleeing from other causes) if they can see a higher-ranking military monster nearby.
• It’s harder to scare troops if there are others nearby (they have effectively a higher resistance).
• Troops recover faster from being scared if there are others nearby.

This doesn’t necessarily have to be only the Yendorian Army; the rule could be extended to all monsters being “supported” by other monsters of their same species, with some special cases for things like all orcs supporting each other.

Barbed orcs, which are more deadly than regular orcs.

Tripe rations should not generate randomly very often, but they should appear in the inventories of monsters that like tripe, such as orcs.
