So if you use your crowbar to push someone off a cliff, that's KOS'able, right (and slayable if they take damage)? But what I'm wondering is, do they have to fall off the cliff? Say I pushed someone near the edge of a cliff, but they didn't fall, that's not KOS'able, right? Also, is it KOS'able if you push someone off a cliff, but into water (where they take no damage unless afk by drowning)? Just confused on these rules.
If you push someone that person takes damage or gets killed, it is a slayable offense. However, pushing someone very close to the cliff (and almost falling and can possibly kill or damag ethem) is a traitorous action as far as I know. If someone sees you doing that, then they have the right to kill you. If you push someone into an area that doesn't harm them (sans the poisonous water on one of the vanilla maps), then that isn't a slayable offense.
