does a short rest restore spell slots - Paladin/Warlock multiclass (max lvl either 11 or 14) rich 888 slot

Depleted spell slots are generally replenished by taking a Long Rest (Short Rest for Warlocks), though there are methods of creating additional slots, or replenishing expended ones.

Restores Spell Slot up to Level 3 once per Long Rest.

But remember that since it consumes the Wild Magic Sorcerer’s Level 3 Spell Slots, you can only use this at most 2 times before taking a Long Rest or converting 5 Sorcery Points into one Level 3 Spell Slot.
