Skill functions and interactions

The explosions from projectiles can overlap. Given sufficient investment into increased area of effect, many explosions can hit the same target. The projectiles from Explosive Concoction are ground-targeted, cannot collide with enemies, and cannot pierce, fork, split or chain; only the explosion hit and do damage. Testing with 9 total projectiles showed that most projectiles will overlap when the radius is 2.0 metres (average 8.8 out of 9), and all projectiles will overlap when the radius is 2.1 metres.

AoE breakpoints: The base radius of the skill is 1.8 metres and follows standard area of effect calculations.
