Long story short: Debuff Reflection > Prohibitions / Immunity Bestowals = Nullifiers / Purifications > Other debuffs / buffs. While Prohibitions are active, Purifications can removed debuffs except prohibitions.  Likewise while Immunity Bestowals are active, Nullifiers can remove buffs except Debuff Reflection, and Immunity Bestowals. Examples:
  • Applying Nullifier to Astrid with Debuff Immunity Bestowal, Regeneration Barrier, Taunt, and Regeneration Bestowal →Regeneration Bestowal, and Taunt will be removed, but Debuff Immunity Bestowal, and Regeneration Barrier will remain
  • Applying Nullifier to Iris with Debuff Immunity Bestowal, Barrier, Taunt, and Charm Counter →Barrier, Taunt, and Charm Counter will be removed, but Debuff Immunity Bestowal will remain
  • Applying Nullifier to Granhildr with Debuff Reflection, Debuff Immunity Bestowal, Barrier, Taunt, and Regeneration Bestowal →Nothing will happen
  • Applying Buff Prohibition to Astrid with Debuff Immunity Bestowal →Buff Prohibition will be activated and Astrid will not get any new buffs
  • Applying Buff Prohibition to Granhildr with Debuff Reflection →Nothing will happen
  • Applying Debuff Immunity Bestowalm, and Regeneration Bestowal to Astrid with Buff Prohibition →Debuff Immunity will be activated, but Regen will not be activated
  • Applying Purification to Astrid with Buff Prohibition, Charm, and Curse →Charm, and Curse will be removed, but Buff Prohibition will remain
