I want to suggest having a system to use the excess xp you get after you hit 30. Basically, it is useless. I would suggest having an NPC in the nexus that uses the excessive XP as currency, able to drain the xp down to the start of level 30. What it would do in return to it is up to the team ofcourse, a few ideas I had are.
1) Making it possible to Imbue self written books with xp, making it possible for the reader to get a fraction of the xp, for example, a wizard writing a book about about magic, imbuing it with 30.000 xp, for anyone to read it, and use it, a spellcraft check would be made, according to the character who infused it, so, if Harry the apprentice wizard with 14 spellcraft, reads a book made by Wolf the Archmage, costing him 30000 xp, he would roll spellcraft, vs the DC, and for each above the DC (per team discretion) he will get a bas of 30%+1% per 3 points above the dc.
I think this will both make use of a useless resource so far, in addition to making it more fun to have an abiolity to actually mentor new chars, adding to the Dynamic of apprentice/master.
2) I would suggest having a unique perks shop using said xp, thus enabling further progression past 30, as a VERY basic example, 2 million spare accumalated XP,l could be used to get wings, or anything the like. Basically use ABSURD amounts of xp, for the ability to get UNIQUE perks to a character, I think it would reward people who stick to a character for a long time and make the "endgame" still fun with a sense of progression.
This suggestion addresses mainly COSMETIC rewards for the xp, not something that gives power, but lets you have things not normally available. I do think, a sort of "Endgame" mechanic, could be hugely beneficial.
3)DM interaction rewards, basically tokens at an EXTREMELY high cost, giving the player the right to have a DM event, for his character, be it a goal he is pursuing, or something regarding his history.
While I am aware this is a very hard demand from the team, if it is accepted, it will let long standing players, the ability to get personal attention.
I would be happy to have other ideas as well to do anything with said "Useless" Xp, and not only make it RCR fodder. Would be happy for opinions aswell.
My main point in this thread, is trying to adress the fact that after 30, xp is useless, and as a resource, I think it can be nice to use it.
Thanks for reading
