Necro lull -- this can't be classic.

[DMN]

I tested this quite a bit back in the day, mainly to prove that LOW CHARISMA didn't improve necromancer charm/mez/lulll abilities. This was an oft claimed urban legend of sorts by people back in the day but i showed it was not true, but also showed that having high charisma did not improve things noticeably either. It appeared that necromancer gained nor lost anything related to charisma. My enchanter on the other hand had clear differences in those abilities. And in order to be on equal footing with my necro the enchanter always needed to be fully geared/buff for cha. My necro could have been naked and ahad the same rates as the enchanter. My enahcnter was NEVER better at charming/lulling/mezzing undead than my necro.

Reading what GZ said in that thread, my guess is that necro's "soft" cap for charisma was extremely low, while enchanters was much, much higher.
