Two retainers. I play since beta and alone 7 pages are glamours. I am 3 star crafter and only whenever I start hoarding stuff like the favor items or all the relic and beasty token I run low on space but what for do I have mogmail storage?
But yea used up a lot beasty token lately for the relic - [turn in for shields -> turn to GC seals -> moonies] and sold the favor items so made some space... plus occasional retainer tetris is a must.
