The attack patterns of this boss and the armour type discussed here: kzbin.info/www/bejne/q3ylYaGsgM19f7s Also forgot to mention that using Ägir instead of, for example, Laffey II on manual playthrough might help with inflicting the armour-break debuff. This requires further testing, though. As of now, I'm quite happy with the results and don't want to spend hours trying different strategies ;P
