Guild Wars 2

Toss Elixir U creates a wall that protects from projectiles, either a smoke field that destroys projectiles or a light field that reflects them. The base duration is 12 seconds, which is meant to be extended to 14.5 seconds with the HGH trait in Alchemy.

However the duration of the field is always only 12 seconds, despite the tool tip being affected accurately, the actual duration is not affected by the HGH trait.

HGH is known to exclude some Elixirs form its effect since launch, especially Toolbelts and Automatic Trait-Elixirs.
