Players are able to obtain items with special rare effects on the servers. When opening Chests or Crates, you have a base of 2.22% chance to get a rare item. This is increased by adding additional Rare Chance to an item. The standard rare item effects are categorized by their "tiers", which were previously based on rare chests that were available in the premium store. As of a Summer 2015 update, these chests are no longer available for purchase; they have been replaced with supply crates.
Additional rare effects are separate from the standard rare tier system and vary in exclusivity and value. This includes robo effects, special and legendary magic dust effects, and any other special effects.
