Hestia, Goddess of the Hearth

C'mon Hestia is important! (Although not well known ;-;)

Description: Should look like Nox in a way. Except wearing White robes. Her hair flows and is much longer.

Role: Support mage, like Aphrodite and Hel.

Hestia: Passive
Burning Hearth. The More Hearths that are set on the ground, the higher her heal and damage is. Also reveals how many stacks are on each opponent. (Max ten)

Abilities:

One: Hearth:
She can put down a bonfire, that can heal nearby allies. Nearby opponents gain a stack within the first second they enter the bonfire's range. After the first second, if they remain in the circle for a longer period of time, it deals one more stack. (Works much like Ah muzen cab Hives and Sylvanus one.) Also works as a ward. (Should have a long cool down, maybe 15-20 seconds.)

Two: Flicker.
A large AOE effect move. Alone it doesn't deal so much damage. If she uses it near one of her hearths, she can make it explode, both healing allies, and damaging opponents. Puts stacks on an enemy. (1-2 Stacks)

Three:Divinity.
Grants divine protection on either herself or an ally. Removes CC effects, and gives them an effect that works like Shield of the underworld. + extra defense, but the damage that gets reflected back to the enemies, ignores the extra defense part. She can use this ability to put stacks on an enemy, and deal damage to them. Should deal little damage to one player if used on opponent. (2 Stacks)

Ult:
Reflective flame. Starts a fire on each opponent with stacks, Deals tick damage, to enemies, one second for each stack. She regains health from the tick damage, and nearby allies also gain the health. However her healing range is a short amount, and she moves very slow while doing this. Much like Ares' ult.

(After writing all this I noticed someone else made a Hestia thread. I suck at damage scaling and stuff so can anyone suggest damage scaling?)
