Are these leveling items heirlooms?
If they don’t work like heirlooms then they are terrible, and for some reason I get the feeling they don’t.
If they do then it wasn’t very well explained.
They are just cosmetic with some basic stats.
They are just weapons which have a bit better stats than the other weapons with the same level requirement (ie 50 power instead of 40 at lvl 30 – I don’t know exact stats, so i made this up).
