I was experimenting with a dueling ranger using the hunter's mark and grabbed colossus slayer at level 3 to try and make a maximized damage character. I discovered though because like with the rogue sneak attack Colossus Slayer is treated as it's own attack both dueling and hunter's mark damage is added on top of it basically doubling my damage as if I crit on every hit.

For example, I'm using a Longsword + Shield doing 1d8 damage from the weapon. My weapon damage is 1d8 + 3(str) + 2(Dueling) + 1d6(hunter's mark)
Now when colossus slayer triggers I deal an additional 1d8 + 2(Dueling) + 1d6(hunter's mark)

Essentially changing what was initially suppossed to be 2d8 +3 +2 +1d6 (8-27 dmg) to 2d8 +3 +4 +2d6 (11-35 dmg)
It's not completly game breaking, but it is a noticable damage boost due to how extra damage features are currently being handled.
