While playing my current EK life it occurred to me that the tree really could really use some love. Particularly when it comes to a Wizard playing a "Tanky" EK.
What I have in mind is two fold, a new type of damage-shield and the means to replenish it.
Specifically...
Mana Shield (Tier 4) - Toggle: While this ability is active, you can use your mana pool as temporary hit-points. (Yes just like the Diablo ability) While the Mana Shield is active, all your spells and SLA's are reduced to touch range.
Energy Siphon (Tier 5) - Your melee attacks Siphon mana equal to +3/6/10% of the melee damage done. You may only gain this effect once per second.
As always, constructive remarks are welcome...
Thank you in advance for your time and consideration.
