One Tvarog runestone is used in the creation of the Dumplings runeword which, when in effect, causes any food consumed to regenerate 100% more vitality (i.e. doubling the amount of health regenerated).
Despite the in-game description urging players to put this rune on a sword, doing so doesn't actually confer any effects. In fact, placing this runestone on a sword raises the sword's level requirement by 1, and is thus not recommended.
- This runestone references quark (Polish: twaróg), a dairy product popular in much of Continental Europe. It is often translated to English as "curd cheese", or "cottage cheese", which is often viewed as a specific type of quark.
- This runestone has no effect when placed in an upgrade slot, and raises the weapon's level requirement by 1.
- In the crafting menu, this runestone's weight is listed as 0.01 when it is actually 0.03.
