ARAM: Mayhem Trait System
The augment Trait System is removed for this season. Some trait bonuses become standalone augments: Archmage (Gold), High Roller (Prismatic), Snowday (Silver), Yowch, My Coins! (Gold, replacing Make it Rain), Wee Woo Wee Woo (Gold) and Stackosaurus Rex (Silver).
Source line
We're removing the Trait System for this season.
  • Earlier this year, we explored how Traits affected player choice and build variety. While some Trait effects, like High Roller and Archmage were very popular, the system also reduced variety in Augment decisions. To preserve the fun parts, we've converted some Trait bonuses into standalone Augments so you can still enjoy their fantasies without being locked into a full Trait.
