Beyond relic/mythic/magians(some really easy options). you can also:
A) Furor Cesti drop from a fairly weak NM, that also drops a 100k+ pop item.
B) turn in dominion credits for Savate fists with up to dmg 24, only 51 delay, and up to crit rate +4%. plus any bad ones npc for 6-7k gil. not like you're using notes for much else besides the occasional screen.
The second options is at worst, free. and at best, easy money.
