Buffs and Debuffs

== Important notes ==
The same effect with the same name and the same icon can have different duration depending on the caster. Taking Immunity as an example, from observation it lasts for around 4 secs when used by Water Basilisk, ~6 secs for Water Crystal Priest, ~7 secs for Water Ranger and ~20 secs for the Steel Widow boss. There are no official numbers given. In addition, some champions can extend their effect duration when they skill up.
New rules in Update 5: Applying a stack of any stacking buff or debuff to a Champion that has the maximum number of stacks will automatically replace the stacks with lowest remaining duration (if the new buff has a lower duration than this, nothing happens). Buff Stealing can now be resisted and uses Caster's Accuracy vs Target's Resistance, similar to remove buff and inflict debuff effects.

==Legendary debuffs & Boss-only debuffs ==
Legendary debuffs work exactly like normal debuffs, except that they can only be cleansed by the Hallowed gear set or by certain champions such as Fire/Water/Dark Mai Shiranui and Water/Dark Dreadblade. The Steel Widow's cleanse ability is unable to remove legendary debuffs.
Legendary debuffs come with a bonus that ignore 50% of the target's resistance. The Resilient gear set can be used to improve resistance against legendary debuffs.
