Mastery Errtels

Mastery Errtels guide for MU Online: requirements, steps, rules and progression information for LigaMU PRO.

Mastery Errtels

Mastery Errtels are upgraded forms of regular Anger, Blessing, Integrity, and Divinity Errtels. They have no rank-up path after conversion; their inherited option count defines whether the result is Normal, Rare, or Unique.

Errtel of Radiance cannot be converted to Mastery. A regular Radiance Errtel is used directly in a Mastery Pentagram's Radiance socket.

The success rate depends on the source Errtel's rank and level and is shown in Adniel's preview. On success, the result is a corresponding Mastery Errtel at +0. On failure, the source and combination materials disappear.

Option conversion: inherited options that name a target element are converted to the Mastery Errtel's own element. Review the before-and-after preview before confirming.
