TERA AINM Solo Priest Last Boss Duras

I managed to kill Duras in 1h 20 min. Shield phases: 5:38, 12:40, 16:56. It took me around 3 mins to break the shield. My highest crits were around 600 k. My gear includes 14 lucid staff rolled for dps, dps schisma gloves, edgetime jewelry, power/carving brooches, innerwear and keen etchings. All is rolled for crit rate. I actually had to kill him twice, because it didn’t record properly the first time and the video ended up corrupted. I wasn’t mad at all. First boss:
