Enhanced Effectiveness to double the int contribution to mana, then stacks int and %attributes then finally %mana to get the largest possible mana pool. the absurd defense comes from this huge health pool using the trifecta of 
Mind Over Matter 
Eldritch Battery and 
Chaos Inoculation . the damage goes off the charts with 
Archmage and talents like 
Pure Power and 
Arcane Intensity to get several hundred, or even thousand percent increased damage. the main skills are 
Spark then a clearspeed setup with 
Blink and a bossing setup with 
Cast on Shock and 
Lightning Conduit

dont be scared by the pathing points, the raw 5 int is actually big for scaling and all of the jewel sockets are powerful with shock effect, %mana on kill, max res etc
Adorned can grab the 2 sockets for 7 points beneath Mind Over Matter , by dropping 6 points with Eldritch Battery "from nothing" jewel, or by dropping Mental Toughness after you get 
Melting Maelstrom
Atlas Tree
How it Plays
the mapping simply relys on having aroudn 4-6% mana gain on kill across 2-3 jewels and you will never run out of mana. bossing can swap to Cast on Shock and Lightning Conduit to kill bosses in a couple hits before mana is ever an issue. Spark with Mobility is just the most drooling easy mapping youll ever do
