Here's a list of the effectiveness I think each weapon should have on the Zulites:

Arrows/projectile Zulites should be natural shields to this kind of thing. If you shoot an arrow at a rock, nothing really happens. With Zulites, the same thing would apply, even though, as Tyhm said, there's still a creature under the rocky exoskeleton.

FireLess damage than humans. You've seen it before... pictures of houses that survived a fire, with only the chimney remaining. Zulites would still get damage, but not much.

Swords When you hit a rock with a pick, hammer, whatever, stuff breaks off. Swords should be almost devastating to Zulites. We're talking almost double the damage that a human gets from swords.

Rolling For rolling, I think that the button pressed during a time of no movement should result in the Zulite curling into a ball, which does almost nothing except maybe add a little extra weight to whatever it happens to be standing on. Maybe in some quests there could be a platform that only moves down if the Zulite is in the curled up position. Anyway, the Zulite should be running when the player presses "a" to get enough momentum to start rolling. A push probably isn't necessary, but maybe as the Zulite walks, it gradually speeds up.
