The fifth weapon skill slot contains the most potent skill of each attunement, assuming you can fulfill the requirements. Each skill starts off in its base state, a quick cast that etches a spell circle into the ground. As an example, the fire skill Etching: Volcano creates a spell circle that grants might to the elementalist. The skill then flips over into Lesser Volcano, a ground-targeted spell that erupts to create several damaging strikes. Unlocking the skill’s full potential requires the spell circle to be completed before reactivating the skill. To do so, the user must simply use three other skills while standing inside the etched circle.
This process isn’t limited to spear skills, so instant-casting utility skills can be utilized to speed things up. Once the spell circle is completed, the skill flips once more to its final form—in this case, Volcano—allowing the user to unleash the full potential of the effect. The full-power Volcano erupts for a longer period of time, creating additional damaging areas and inflicting more damage than its lesser version. Other attunements utilize the same etching process, but each has their own flavor and skill effects.
anyway I can't believe spear elementalist is pictomancer with more DPS and less support. might be worth picking up as a SECONDARY weapon just for that
