better handling of rake bleed immunity

 For Warlocks with the Malediction talent, when checking if Curse of Recklessness, Curse of the Elements, or Curse of Shadow is already on a target, the addon will instead check for Curse of Agony to allow you to refresh agony using them. This is enabled by default and can be disabled per-command with `malediction=0`. Don't use the `refreshtime` option with this as the server won't refresh Curse of Agony if it is still on the mob.
 
+Special spells such as `Rake` that deal direct damage but also apply a bleed DoT are handled differently from normal debuffs. When one lands, Cursive starts a 1 second timer then checks that the bleed aura actually appeared on the target. If it did not, Cursive removes the curse.
+
+If that verification failure happened while the target was not at the client buff/debuff cap, the addon assumes that mob name is bleed-immune and caches it in memory. Future casts against mobs with that same name will skip bleed tracking so you do not keep getting `Rake` timers for 1 second on bleed-immune targets.
+
 Mobs with raid marks will be displayed first.
 
 Mobs will the top 3 max hps will always display next. I may make this configurable in the future.
