Beseech Thy Patron

Prerequisite: 18th Level

You perform a 10 minute ritual in which you beg your Patron for assistance during especially dire or significant circumstances.

If you have not attempted this ritual within the last year, the ritual automatically succeeds. Otherwise, roll a charisma check against a DC equal to 20 minus the number of months since your last attempt.

On a successful save, the ritual succeeds and your Patron infuses you with power, empowering you in their name.

For 24 hours you gain a +5 bonus to your AC, all ability checks, saving throws, and attack rolls; your number of spell slots triples and you regain any you have used, and your appearance is modified as little or as much as your Patron sees fit, to better signify their presence.

Additionally, your Patron immediately casts the wish spell with whatever wish you choose, though your wish still might not be granted as per the spell description.

However, such wondrous assistance is not without cost. At the end of the 24 hour period, you lose all Warlock abilities except your cantrips. You have zero spell slots, zero invocations, no pact boon, no mystic arcanum, and no Patron-specific abilities. You regain all abilities at the end of your seventh long rest.

On a failed save, the ritual fails and you suffer consequences depending on how many times you have ever failed this ritual:
