Most basic skills have an elemental attribute type. The skill's damage will increase if it has the same elemental tpye as an equipped pentagram. This is known as skill imprinting.
  • When a skill and pentagram share a common elemental type, skill imprinting is activated.
  • Imprinted skills will display a small elemental icon in the Skill UI.
  • Each skill's imprint has a unique skill damage percentage increase.
  • Elemental Imprint is determined from the pentagram's properties:
    • Pentagram's tier
    • Pentagram's base level
    • Base level of any errtel inside the Pentagram
  • [Elemental Imprint] * [Imprint DMG %] = [Increased Skill DMG]
