Powerlevelling fix?

[asphodeli]

Probably insanely hard to implement, but here goes. Have an airship amenity that gives a negative X level buff which lasts in death, dungeons and after shrining, and in regen zones until you manually remove the negative X level buff (through the same airship amenity). This would allow level 20s to group with level lower level characters for XP, though the issue of stat points, spells and twinked items remain, which I have not come up with an idea yet to solve them.
