Earning 0 petal when killing mob

"

If a player fails to complete a memory thread map (either by using up all portals or letting the instance expire), the map can be attempted again; however, it will remove all existing Memory Altar modifiers and gain the unremovable enchantment Area is Cursed. This modifier penalizes item drops, player experience, and restricts certain content from appearing. It has no relation to curse skills. It also significantly reduces the number of memory petals obtained and prevents Exarch or Eater influence monsters and altars from appearing.
