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.

AoE breakpoints: The base radius of the skill is 18. 12% increased AoE gives the skill a radius of 19, 24% increased AoE gives a radius of 20, and 37% increased AoE gives a radius of 21. Testing with 9 total projectiles showed that most projectiles will overlap when the radius is 20 (average 8.8 out of 9), and all projectiles will overlap when the radius is 21
