This intricately sculpted platinum ring resembles the two-headed serpent of legend.

When attuned to this ring, you can cast a spell that requires concentration even if you are already concentrating on a spell or effect, provided the combined level of the spells is no greater than 10. While concentrating on two spells in this manner, the following conditions apply:

• Your movement speed is reduced to 15 feet.
• At the start of your next turn, you take 2d6 force damage. At the start of each following turn, the force damage you take increases by 1d6. This damage cannot be avoided or reduced in any way and does not force a concentration check.
• Any time that you are forced to make a concentration check, you must do so separately for each spell and failure ends that spell as usual.

Once you have used the ring in this way, you cannot do so again until the next dawn.
