D/any Pious Renewal/Mystic Sandstorm

This build takes advantage of Pious Renewal's energy and health gain when removing multiple enchantments with Mystic Sandstorm, resulting in spike damage and bringing you back to near full health and energy to remove downtime.

Attributes and Skills

Equipment

Radiant armor.
Insightful Staff of Enchanting
2 Earth Prayers rune, +3 Mysticism rune, Superior Vigor rune, and two Runes of Attunement.

Usage

Before engaging, cast in order of Enchantment duration:

Aura of Thorns --> Heart of Holy Flame --> Vital Boon --> Armor of Sanctity --> Mirage Cloak --> Pious Renewal then get near an enemy or a group of enemies and hit Mystic Sandstorm. This will result in:
130 damage from Mystic Sandstorm to nearby enemies.
75 damage from Mirage Cloak to nearby enemies.
30 energy from Mysticism.
12 energy and +60 health from Pious Renewal
200 health from Vital Boon
4 seconds of burning from Heart of Holy Flame
15 seconds of bleeding from Aura of Thorns.
Casting Armor of Sanctity shortly after sandstorm can help reduce damage against those you inflicted bleeding and/or burning on.

The health and energy gain should leave you enough energy to repeat the process.

Counters

Massive enchantment removal before Mystic Sandstorm is launched.
Anything preventing the casting of enchantments on you.
Repetitive knockdowns and interrupts to fail enchantment spells.
Kiting.

Variants

Pious Renewal can be replaced with Arcane Zeal. This reduces your health gain after using Mystic Sandstorm, but it allows for more costly, more powerful enchantments to be used instead. For example:

Arcane Zeal

Vital Boon

Dust Cloak

Heart of Holy Flame

Staggering Force

Mirage Cloak

Mystic Sandstorm

Optional

By sacrificing a few points in Earth Prayers and placing them instead in Scythe Mastery, you can provide yourself with an acceptable alternative should you find yourself up against an enchantment-remvoing or interrupting foe.
Despite the health spike after casting Mystic Sandstorm, it's very easy to get killed while casting the enchantments. For this reason, Mystic Regeneration works very well when used as your first enchantment.

Notes

The order of the enchantments casted may be mixed, for example if a ranger is attempting to interrupt your enchantment spells, cast Mirage Cloak first and proceed onto the rest of your enchantments. Also, Heart of Holy Flame has a longer cooldown, so you may cast that last if necessary. This may even help the spike damage if done last due to it's 60 holy damage effect.
If someone is trying to kite you, you may also cast Aura of Thorns near them to inflict cripple, then proceed to the rest of your enchantments.
