Mainly for pomegranates and giggles, but how much would one theoretically need?

1. A base test- No %boss, no %damage except from Epic Adventure and Coin Flip (in order to actually raise the limit to the 70m cap), and no Assassinate- Reinforce. Uses Dark Sight+Assassinate and 5 Killing Points when available.

2. The "average" level 200. 100%boss, Kanna+Demon Avenger Link Skill, %damage from Epic Adventure, Coin Flip, So Gong's Gloves (+12%) and Assassinate- Reinforce. Again, uses Dark Sight+Assassinate and 5 Killing Points when available. I'm probably forgetting something here.

Not sure on:
1. Dark Sight+5 Killing Points+Assassinate= 4.0x or 3.75x more damage?
2. Is Coin Flip's damage cap boost's total stack equal to 5m or each stack is 5m after Unlimited? Because 90m is lulz.
