The usual forum bug

Wow thanks to this topic I finally solved my misunderstanding that 10% was 11%. Or sometimes 12.1%.

It only really looks funky when you try to pile all the dmg%s all at once.

In game scenarios its much more fluid and predictable increases.

Lets pretend that Im backstabbing something for 10,000 (target above 50%) and I have executioner trait (+20% dmg below 50% hp) I know as a player, when that target hits 50%, that backstab will start doing 12,000. This is because of the multiplicative modifier.
Multiple multiplicative modifiers may look complicated compared to 0% damage but it’s much more reliable to expect damage increases. (vuln stacks changing aside xD)

Also, calculating it is actually pretty easy too.

Preliminary math lesson: Percentage whole numbers, when multiplied/divided start at the 0.0_ digit. So we logically know 1% of 100 is 1? Well, 100 × 0.01 = 1. We will be using this idea when calculating multiplicative modifiers. Increasing a base (100%) by +5% is equivalent to x1.05 (105%).

Start with 100 (100% base damage)
Add in 10% modifier = 100×1.1 (110% damage) = 110(%).
Throw in another 10% modifier = 110×1.1 (110%) = 121(%).
Lets throw in a 20% modifier = 121×1.2 (120%) = 145.2(%) damage increase.
At the end you can subtract 100 from the values (this takes away the % granted from base damage)
In this example, +10%, +10%, +20% = 45.2% damage increase.
