Wrong Radius of Skills supported by High-Impact Mine
"Increased Area of Effect of Aura Skills" causes skills supported by High-Impact mine to gain increased AoE, although it doesn't work in-Game, easily tested by using the reservation mastery "30% increased Area of Effect of Aura Skills" and using a random spell like shock nova with either blastchain-mine and high-impact mine. There is no area difference between both.
Bumping this.
PoB still suggests that the passive tree modifier "Increased Area of Effect of Aura Skills" works with skills linked to High-Impact Mines support. It should not. It should only apply to the radius of the "chance to deal double damage" aura that High-Impact Mines innately comes with.
This is very easy to visually confirm with linking Vortex to High-Impact Mines and swapping to Blastchain Mines. With a level 1 Vortex skill gem linked to High-Impact mine support having a base 2.0m radius, taking all of the "Increased Area of Effect of Aura Skills" on the passive tree increases the radius to say 3.0m radius. Swapping this to Blastchain Mines in PoB removes the aura tag from the skill and so uses the 2.0m base. In game, the Vortex visuals look the same for both supports, suggesting that PoB is incorrectly assigning the aura tag to the Vortex skill.
The modifier does work with base mine skills like Stormblast mines, both the aura and the detonated effect. This is reflected correctly in game and in PoB.
