How to create errtel & Pentagram Mastery
To access your Pentagram equipment, open your inventory by pressing the [I] or [V] hotkey. You'll find a dedicated section for Pentagrams. Each Pentagram includes 1 to 5 slots where you can insert Errtels to boost your elemental power.
The 5th Errtel Slot is initially locked and can only be unlocked using an item called the Expansion Scroll of Radiance Slot, which can be acquired as a drop from bosses or crafted through specific combinations.
When creating a new character, you automatically receive a starter Pentagram, which can be equipped in the designated elemental slot. To quickly equip it, hold the Alt key and Right-Click on the Pentagram.
What Is the Elemental System?
The Elemental System is designed to create balance between newer and more experienced players. By using elemental strengths and weaknesses, players can overcome power gaps in both PvP (Player vs. Player) and PvM (Player vs. Monster) scenarios.
This system introduces Elemental Damage and Elemental Defense, which are separate from your standard stats. Elemental damage is shown in a distinct color during combat, depending on the type of element used (Fire, Water, Earth, Wind, Darkness, etc.).
To benefit from this system, you must equip a Pentagram, which unlocks elemental combat capabilities through slotted Errtels.
Errtels Information
The errtels are the items that the pentagrams is composed.
There are 5 types of errtels and each type has 5 different elements.
Each errtel can have '3 ranks' (in the future, maybe it will be 5) and each rank can have '10 levels'.
You can insert errtel of any elemental type into pentadram.
When errtel is inserted into a pentagram item, it will add the additional options listed on the errtel item to the pentagram.
