On her broad and magnificent road to hegemony, Muriel has often been seen with this particular build.

Her support power for the whole of the team is unparalleled.
 
Ruleset

Mage, Shield

 
Build costs: Normal (17500 Gold, 2917 per Item)

Starter enemy: Duo Lane
Evade enemies: Controller

Powers:

• Magical Power: 600, see calculation
• Mana Regeneration
• Ability Haste: 70 + [Chime] + [Ravenous]
• Shield destroyer: [Event Horizon]

Weaknesses: Mana and Haste in early game (like most Muriel sets)
Redemption: See High MR-AH Starter

Reminder: Magical Power has way more multipliers than Heal & Shield Power. Look at your ability stats and do the math!

Replace Marshal with Crescelia or Totem when your Carry is Revenant. Attack Speed does not support him (so much).

Replace Marshal with Leggings in late game when your 6 slots are full. AS +15% at high levels does no longer have that strong effect on most heros than at low levels.
 

Calculation

Full set, L18, HSP not included (shields +12%)

Bonus Magical Power when Shield is up (Veil)
450 MP +15% +30% = 600 MP
600 MP +45 +12% = 722 MP (late game, enemies below 40%)

Alacrity (RMB) Shield, every 3s
170 Shield-HP + (600*25% = 150) = 320 Shield-HP

Alacrity (RMB) Attack Speed, every 3s
+25% AS + (600*8% = 48)% = +37% AS

Serenity (Q) Piercing Bolt, every 4s
245 MP + (600*40% = 240) = 485 MP

Consecrated Ground (E) Protective Bubble, every 5s
220 Shield-HP + (600*40% = 240) = 460 Shield-HP

Consecrated Ground (E) Bubble Explosion, every 5s
160 MP + (600*50% = 300) = 460 MP

REVERSAL OF FORTUNE (R) Shield, every 68s, 54s (1x Rav), 44s (2x Rav)
650 Shield-HP + (600*125% = 750) = 1400 Shield-HP

REVERSAL OF FORTUNE (R) Arrival Bomb, every 68s, 54s, 44s, 35s, 28s, 22s
225 MP + (600*40% = 240) = 465 MP

Tranquility (Crest), every 40s
150 Heal-HP + (600*50% = 300) = 450 Heal-HP

Sentinel (Muriel Passive Ability)
+10 MP On-Hit + 36 + (600*10% = 60) = +106 MP On-Hit
