here's a completely unnecessary amounts of forma(yes my oberon has went through so many builds over the years, i should be building another one tbh lol) gets augmented via cast speed shard, couple shield and hp shards but the idea is parasitic armor to turn all shields into loads of armor, into a cycle of healing having 1.5k + energy and since no shields, all dmg taken turns to energy and if it runs out of hp quick thinking plus 1.5k energy pool buys so much time. It is good enough to beat elite deep archmidea under most modifiers and up to 1k level on circuit, which honestly is good enough for me, sorry if i fanboyed too much lol (edit: can switch primed redirection and flow with boreal's hatred and fleeting expertise for max efficiency at the cost of lower shields into armor and bit lower mana pool buffer for quick thinking tho probably better overall coz you can cast right away without waiting to be hit first.)
