eadly Characters are those which appear on the who list under the section titled "Deadly Characters" (type 'who deadly'). A character must be level 5 AND 18 years of age to officially become deadly; if you are a pkill character who doesn't fill these criteria yet, you will not appear under 'who deadly' and are NOT yet able to pkill.

Deadly characters may not:

• multi-play while using a deadly character
• be shared
• receive help (healing, shielding, portalling, etc.) from non-deadlies
• receive Immortal corpse retrievals or reimbursements - no exceptions
• attack players more than 5 levels outside their own
  • includes picking up disarmed weapons from someone outside your range
  • includes healing a fighting character outside your range
  • includes looting the corpse of someone outside your level range

Deadly characters are allowed to:

• pkill another player who appears on the deadly list ('who deadly') who is within 5 levels of their own.
• loot the corpse of the fallen deadly player, provided they were the tank or dealt the killing blow.
• use mobs within or lower than the pkill level range of the victim

Warning:
Going AFK or link-dead in a non-safe area leaves you open to attack; a deadly is open to attack every second online, link-live or not.
