cgh Discord is probably better. The bugs thread is dedicated to passing bugs along to Sierra Lee.
I wrote that section. Lilith does not resist Blind or Silence. Unified Strike does have a 100% chance to inflict Blind, Silence, and Stun. These are facts.
However, Lilith has 999 LUK and that reduces the chances that she receives status effects. I'll update the Bosses page to reflect this.
Note: Information / strategies added to the wiki are never bugs to be reported to Sierra Lee.
