This build is a simple one bar build designed to deliver maximum damage through status effects in the Endless Archive.
To actually play the build, simply use your ultimate sparingly to take advantage of the health recovery from strategic reserve, keep your leeching vines up, arctic blast to burst heal when necessary, arctic blast to stun when needed, or arctic blast to reapply the damage over time functionality. Otherwise, place your Winter's Revenge under a group of enemies, and Force Pulse the various Fabled mages in the Endless Archive.
Your status effects will enable massive area of effect damage, especially if you get the pictured Vision in the header: “Focused Efforts.” This one vision will take your damage and skyrocket it, allowing you to quickly clear all the way through at least Arc 5 of the Endless Archive on your own in around 2-3hrs. The more of these Visions you get, the faster and further you can go.
