What makes twinking a caster "great"

[zelld52]

From what I understood from a different post, the charisma check on charm tick is insignificant compared to the level difference and mob MR.

Compared to critical on pacify resist and initial charm cast where charisma is a more significant figure in the equation compared to the same level difference and mob MR.

On mobile, I can dig for the forum post I believe I have it bookmarked. It’s likely a case of different posts having different influence but I do have some anecdotal evidence.

Levelled both a Necro with netted kelp and 25 CHA and enchanter with 200 CHA same spots per level progressing through Howling Stones, and the necro never had a problem with early charm breaks - neither did the enchanter. However, the necro had significantly more crit resists on pacify (close to 33% crit on resist) compared to much more like <10% crit on resist pacify on Enchanter.

The necro additionally had more resists on the initial cast of charm than the enchanter, who rarely had a resist on charm unless the mob was a tougher target.
