Undecember is a top-down hack-and-slash RPG game akin to games such as Diablo and Path of Exile. As fun as it may be to defeat hordes of enemies and collect awesome loot along the way, there is that distinct satisfaction players could get out of building their characters how they want them to be.
One of the most exciting features that this game offers is the rune system. It allows players to customize their play styles to some degree as it determines the skills your character may use through its equipped skill runes. While this feature isn’t new to the genre, Undecember adds new wrinkles to it, for instance, the ability to upgrade the runes you currently have to make them stronger.
In this guide, we will be looking at how players can upgrade their rune grades in Undecember.
How To Upgrade Rune Grade – Undecember
First off, keep in mind that there are two types of runes in the game. One is the skill rune that contains an active skill, and the other is the link rune which provides various buffs and effects when linked to your active skill.

These runes start with a Normal rarity rating by default with only a single modifier in them.
That being said, you can enhance each rune’s modifiers and even add more to the mix by upgrading them. To do this, head over to Mystic in town and choose the option: Rune Enchant. This will lead you to the Rune Enchant interface.

Here, simply choose the rune you want to upgrade. To drive the point home much easier, we will be using a rune that has Normal rarity for now. After deciding which rune you want to upgrade, review its effects and then click on Register.
This will then put the rune you selected on the rune slot to the left of the screen. As you may notice, just below it is a handful of more options on how you may want to modify the particular rune.

Say that you want to upgrade its grade to Magic; then you’d need a link rune to do just that, particularly a Link Rune Magic Upgrade Essence. The requirements to upgrade your rune’s grade are indicated in the left panel as well.
Once you have the necessary materials, click on the enchant button at the bottom of the left panel. This will convert the rune to Magic rarity while also adding a random modifier to it.

Let’s say that you still want to upgrade the rune and elevate its rarity to Rare. To do that, click on the Link Rune Rare Upgrade Essence option. Needless to say, you also need to have the necessary materials in your inventory to use this option.
Final notes: as satisfying as it may be to keep on upgrading your runes, keep in mind that the higher the rune’s grade is, the more costly it will be to upgrade.
There you have it! Now you know how to upgrade your rune’s grades. Runes are crucial to master to be successful with this game. Make it a point to always visit the Rune Enchant option and keep upgrading those runes!
