Patch notesCleaned up how boons are distributed. Previously some levels gave stat bonuses and some AP/Unlocks, now every level gives one of each. Power rebalanced on abilities and items to be the same overall as before. Total AP given out reduced from 32 to 29, total stat levels increased from 20 to 32 (but rescaled in value such that they are the same overall as before).

Patch notesShortened the channel time required for max duration/damage.

Patch notesThe spit debuff is now a heavy slow rather than an immobilize, and its damage is dealt over the effect's duration rather than all on initial impact.

Patch notesThe active's duration and damage are halved if Fathom is not latched to a wall while casting.
