Crown of Resolute Focus (Patreon)

Most spellcasters only dream of having the focus and mental fortitude required to concentrate on multiple spells at once. Wearing this crown gives you the chance to fulfil those dreams, but beware, holding concentration on multiple spells is harder than it seems.

*Wondrous item, very rare, (requires attunement by a spellcaster)*

✦ This crown has 3 charges, and regains 1d4 charges after a long rest.

✦ If you cast a spell that requires concentration, whilst already concentrating on a different spell, you may spend a charge to maintain concentration on both spells. At the end of your next turn and at the end of every turn following that, you must roll a d4. ON a roll of 1 you lose concentration on both spells, on a roll of 2 you lose concentration on the higher level spell (if both spell levels are the same you lose concentration on the first one you cast, on a roll of 3 you lose concentration on the lower level spell, or the most recent cast, and on a roll of 4 you maintain concentration on both spells.

✦ If you attempt to cast a third spell whilst concentrating on two spells, you must first make a Constitution saving throw to maintain your concentration. The DC is 10 + the combined level of both spells. On a fail you do not succeed in casting the new spell and must roll a d4, following the outcomes listed previously.

✦ Whenever you take damage while you are concentrating on two spells, you must make a Constitution saving throw to maintain your Concentration. The DC equals 10 + the combined level of both spells or half the damage you take, whichever number is higher. On a fail, roll a d4 and follow the outcomes listed previously.

Additionally if anyone wants me to design any specific homebrew items, spells etc. for their game just let me know!

Happy Homebrewing!
