TL;DR lulls should have unique resist modifiers that are not yet implemented but should come eventually. This will make things more difficult 50+
My personal theory is people in classic remember failing lull a lot because they were trying to lull ~even cons with starter charisma. My research also found that people barely cared about charisma back then. My naked brand new ench on p99 in 2024 was getting like 25% crit lull fails on steamfont kobolds which tracks but if they're saying they found a resist layer they haven't put in we'll see.
What sucks is chanters and necros have ways around this (reverse charming or resetting fights) but pallies/clerics/bards, not so much.
