Revised Inspiration Keystone Idea

So since there were a bunch of people whining about the idea of an Inspiration Keystone having a damage factor to it I decided to revise my idea. This new version kinda works like the current version of Dark Harvest, but is all utility.

Arc Beacon Enchants your trinket with the effect 'Arc'.

ARC: Your trinket acts as a battery to collect electric sparks from minions and monsters you kill, as well as from enemy wards you destroy. You gain 5% Movement Speed while you have at least 10 sparks. Using a charge from your trinket consumes all sparks you have collected to heal for 3 health per spark, and grants you Beacon.

BEACON: Gain a shield that absorbs 50 - 250 (+ Total Number of Sparks Consumed through out the game) (+ Total Number of Wards placed) damage. While you have no charges on your trinket you can gain a weaker shield that absorbs 75% as much damage by standing near an ally ward for 5 seconds while out of combat.
