Well, if you want to shop at Eltoora's store you'll need reagents.
If you can cast mage spells and/or use scrolls, you'll also want to save those reagents... Ask Eltoora for a quest. The first time you recover an item, it'll become clear to you.
If you're NOT a spellcaster, though, don't bother. Just save a few berries and knuckles so you can shop at Eltoora's, just in case, and ignore the rest.
