where is the magic store in Chapter 2? In Port Llast?
Yah, top of hill is Eltoora store.
I tell you what I do with all little stuffs then you decide...
There a pool next to Eltoora where I load all those knuckles, berries, silk gland, crystals... all that stuff. Eltoora always want one of those to open store so there they handy and not need to mess inventory with crap. If you arcane toon, can use some stuff to make items in lab after her books are found by you so get quest. But IIRC may need cloak from Ch1. Not sure anymore cuz very long since play this game. Maybe I think of Ch 3.
At Kendrack I use chest in middle of room to keep all quest stuff cuz I give up most quest stuff all at one time b4 going to Luskan. It handy for me but maybe not for your playing. Also good for stuff that won't sell with zero gold like that oddball fire gem or pieces of arrows/bolts instead of spreading all over floor. Can use any chest to store all stuff b4 chapter end but don't forget it there!
