Skill Imprinting
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]
