DRG used to have a non-target AoE attack called Ring of Thorns, but it was was removed ages ago alas (some DRG npcs still use it though, like Alimbiert of the Spiked Butt in that FATE in Coerthas Western Highlands), mostly due to an oversight where players could use it even in cities and so would constantly spam it for lulz. It got so annoying SE just decided to scrap it completely, which is a shame as it was a powerful attack. As usual, this is why we can't have nice things.

There is still Dragonfire Dive and the new Stardiver which are AoE attacks. SO DRG is not entirelly devoid of AoE abilities.
