I used my own world instead of Glorantha. To add to it, I converted monsters and spells from other game systems as well as made my own. Lots of these are not 'Glorantha' like but maybe those of you who don't mind doing their own thing may have some use for them. I like potions as expendable items that low-power characters can use to even the odds and make bad guys more interesting. Check out the nice variety.
Items Here are a wide variety of arrows and some other pilfered items.
