Talents & Mantras
Preshrine essentials are: Flame Within, Brick Wall, Phoenix Flames, Heretic's Sutra, Reinforced Armor, Piercing Will, Pyromania
Postshrine essentials are: Speed Demon, Evasive Expert, Lose Your Mind, Spinecutter, Nullifying Clarity, etc.
Explanations
40 FLM: Flame Within procs Charged Return and Speed Demon consistently, along with giving a 10% damage boost. This in total gives 50% damage multiplication.
30 STR: Lose Your Mind is a 20% Damage boost at max, Spinecutter is just free damage.
100 FTD: Brick Wall, Reinforced Armor
25 AGL: Evasive Expert, Time To Go, Speed Demon
5 INT: Nullifying Clarity
100 WLP: Piercing Will, Brick Wall, Heretic's Sutra, Blindseer
Enforcer's Axe: This build has insanely consistent Speed Demon procs, so it's better to go Enforcer's Axe than Evanspear Handaxe, as Speed Demon does not work on Evanspear. It also has the highest damage output of axes, and no endlag.
Blindseer: Tranquil Circle, Mindsoothe, Cool blue VFX
Ardour: Free damage
Theoretical Output
This build can easily reach the damage multiplier cap, even with halving effects.
Nullifying Clarity (10%) + Charged Return (10%) + Flame Within (10%) + Speed Demon (30%) + Ardour Scream (25%) + Isshin's Ring (20%) = 105%. Apply the soft cap equation (Damage = 50 + ((Base Multiplier - 50)/2)) and you get 77.5%, which is slightly over the damage cap. CONSISTENTLY. You get a consistent 75% damage boost with this build.
Playstyle
Use Flame Within at the start. Spam Ardour Scream. Avoid dodging. Win.
Notes
Isshin's Ring is optional. If you find you're taking too much damage, you can take it off and instead take buff mantras such as Reinforce. This decreases your damage output slightly, but is debatably better than Isshin's.
