All non-sellable non-convertable should be able to store in there... and what is the point of spirit-bound on non-convertible items and why reset spirit-bound on non-convertible and i think only some non-sellable, non-convertable

i'v already discarded Questline Garlean Uniform few days after i finished that, needed space back. and still low on space, really hard to try to level each crafting class almost evenly with low space. I think they should also should allow a 3rd retainer 1 for each city, maybe one that can't sell...
