Player killing is decided the instant you cast any hostile spell or make any
aggressive action against a non-deadly player. Actually killing the target means
little. The only form of player killing allowed is between players whose names
appear on "who deadly" section of the who list. A battle between non-deadly
characters is still illegal even if those who are involved have agreed to the
combat.
Being involved in an illegal pkill is a serious violation of law, and can result
in a stay in hell, slay, loss of all equipment, freeze and/or deny or site ban.
