You'd need level 40 ES to achieve 95%. It's definitely possible but lots of prebuffing. Including 9x Lightning gcs, full prebuff gear and Memory.
and yes, max telekinesis is recommended to make each point of mana more valuable
/edit
Okay maybe not doable without a single hard point in ES.
The post below explained it best.
+3 Helm
+3 Ammy
+3 Ormus
+2 SOJs
+1 Arach
+9 Memory
+13 Inventory
+1 Battle command
=+35
