Wayfinder - Nightmare Echo Farm Loop with Senja

Nightmare mode dropped a few days ago and I levelled as Niss, then switched to Senja and awakened both her and her weapon to lvl 5. Naturally, need to farm all the good echoes. This is my quick round trip for some valuable lvl 30 epic echoes. Some are very high AP like Grazer, Shuul Mydra, Primeval Shurrk, Woe (shown in that order) and some WP related ones especially in the Frostmarch. Repository of Knowledge is my starting point. There is sometimes a summon event there, which will have 3x Shuul Mydra mages and sometimes Primeval Shurrk. There may be 2-3 of these events happening and in fact you can simply loop in between them as they keep popping up after you conclude them. Tyran's Bane (HP/BreakPower) is on the way, so I stop by and kill the Sages I see on the way. Then, I switch to Frostmarch. You need to load a region for respawns, so going between Highlands and Frostmarch takes care of refreshing them. I start at Bone Orchard and head for the event directly behind you when you spawn. A lot of enemies drop WP related echoes here. Event has boss after boss. You get Bonebinder (AP, Mag Def), Kahl Vuul (HP/AP), Key master & Tarkan (HP/Break Power), The Trapper (WP/AP ) , Talon (AP/Crit Power). I finish byAncient One (Crit Power / Break Power), not so important but I enjoy dropping by. There are lots of enemies and trying to get epic echoes takes some time but it is fun. As for Senja, well, she is mostly built. I am still using my heroic build in nightmare. Using rush echoes: Mythic: Teryssa the Silence Dark Star Nigh Maw Slyv'r Mythic: Renegade There is very high burst / aoe damage especially in opening. Unbuffed 15.6K WP, 8K AP, 6K Physical Def.
