Despite being a common foe on overworld maps, Orcs in towns are almost never aggressive. (The one in a cell in Castle Barataria is the only exception.) Overworld Orcs will run the moment they take damage, so your best bet is to have a Weapon and Strength that deal at least 16 damage per hit. This will take out Orcs in one hit, and ensure that you can kill any Creature that is running or is returning after doing so.

Dungeon/Tower Level 00–15
The Orc is the most basic dungeon Creature, which can appear on any level of a dungeon or tower. Orcs have the lowest HP of any Creature, though by level 15 it's still quite substantial. They have no special attacks, but since all Creatures' attacks scale at the same rate, they are always dangerous.
