Руническая табличка Фимбултыра

Runes are way more powerful than most people think. However, to understand their full power, you must have drunk from the Well of Mimir. A rune ritual will require a shape of runes on the floor. To put runes on the floor, you need rune holders. A special type of rune holder is required for the central rune. You'll get back all the runes except the central one. The shape can be rotated and flipped, but it must be all on the same Y-level. A ritual may also require specific ingredients that

need to be thrown near the central rune holder. Some rituals also require mana. You can provide this through mana tablets and mana bands in your inventory. To start a ritual, right-click the central rune holder with a Wand of the Forest. If a ritual gets interrupted, it'll be reset, and you'll get back everything except the mana you paid.

The Rune tablet of Fimbultyr will be dropped when the Guardian of Gaia II is slain by a player who has acquired the Knowledge of Mimir. It is used as the central rune in the most powerful rune rituals.
