Damage output of the Marais Executioner Sword’s skill is ridiculous.
For those curious:
NG+5
RL 181
45 vigor
23 mind
40 endurance
50 strength
25 dexterity
7 intelligence
35 faith
40 arcane
Shard of Alexander (15% more skill damage)
Godfrey Icon (15% more charged skill/spell damage)
Rotten Wing Sword Insignia (Max 13% more damage)
Millicent’s Prosthesis (Max 11% more damage)
Bloodsucking Cracked Tear (20% more damage)
Thorny Cracked Tear (Max 20% more damage)
Rallying Cry (Commander’s Standard skill - 20% more damage)
Howl of Shabriri (25% more damage)
(Golden Vow and Rallying Cry DO NOT stack. It was an oopsie that I cast Golden Vow.)
Max possible damage for a fully charged skill use comes out to a 358% base value. (1.11 x 1.13 x 1.15 x 1.15 x 1.2 x 1.2 x 1.2 x 1.25 = 3.583
One fully charged skill use can bring you to the maximum damage bonus of the Insignia, Prosthesis, and Thorny Cracked Tear. The downside is that bosses usually don’t stay still long enough for that to happen.
