Category:Skills with linear AoE
Skills that creates at least two areas of effect affecting "all targets in a line"; i.e. strikes all foes between you and your target.
Annihilator Beam's Notes section is a decent description of how the line attacks work mechanically - it's just a lot of AoE circles in a line to approximate a linear area. There are four skills using that setup... They all work basically the same, with individual variations for timing, animations, etc... All sorts of AoEs shapes are technically possible - the most unusual thing about the line aoe skills is their delayed timing. After that, it's all geometry and collision calculations.
