So the party in my game fights some intermediate and greater demons. They win, but not before Moonlight (unicorn cohort) dies and will need a Res, thereby losing a level. Bender (another cohort) is also behind due to crafting + house rule allowing another willing creature to pay XP crafting costs. In other words, he covered his own equipment.
Uzelli is a PC, who is down about half a level due to heavy crafting.
One of my players responds to a post I made suggesting ways they could recover from being three levels behind.
Bender, Uzelli and Moonlight can go do sidequests to get some extra xp.... titles of the action
Dorothy and Tin Man... back in Oz Again! (Bender and Uzelli gets transported to another Plane. The adventure isn't over until Uzelli levels and is forced to take Plane Shift as her new spell.)
Hottie and Horny and the Fisting Machine (threesome! Bender gets a Battlefist in the adventure)
101 Orcs (Moonlight vs. an advanced Orc horde... because she won't get XP for low level orcs)
Unhorned and Unhallowed (A powerful curse made by a Lich removes Moonlights horn and she's left without most of her powers. For reasons only low XP can explain.. only Bender can help her. Bonus is Moonlight gets a 150% share of xp for going thru the adventure without her horn. Twist? Benders negative weapon is no help against the Lich.)
