Offer Magic Stones at Rum's Spring to obtain artifacts that help you on your adventures.
There are 34 artifacts in all.
An artifact you have already obtained is removed from the spring, so you never get a duplicate.

Upgrade a drop rate all the way to +100% and the drop chance becomes double the original.
S and A rank artifacts can be upgraded up to Lv.20,
and B and C rank up to Lv.25, by spending Magic Stones.
The number of Magic Stones an upgrade needs depends on the artifact's rank.
