"Title skill" refers to a skill related to a title. There are two subtypes of title skills: skills with a linked title rather than a linked attribute, and technically unlinked skill with a variable effect dependent on title rank.
Unlike other skills, title skills do not have a smooth progression. The only exceptions are Sunspear Rebirth Signet, Lightbringer's Gaze and Lightbringer Signet, which scale linearly with Sunspear or Lightbringer rank.
|Effective attribute rank||0||1||2||3||4||5||6||7||8||9||10||11||12||13||14||15|
|Deldrimor, Norn or Sunspear rank||0||1||-||2||3||-||4||5||-||6||7||-||8||9||-||10|
- Signet of Illusions will work with title-based spells as well as attribute-based spells.
