Ring of Selfishness – Cursed Item – 13th Age
It’s not even worth a second glance, but once you place this ring upon your finger, you wouldn’t take it off for anything.
This dull, unassuming ring provides its wearer with a +1 benefit to the escalation die. However, the wearer’s allies receive a -1 penalty to the escalation die.
Once this ring is put on, it cannot be removed. How it can be removed is something the GM can decide.
