On Homestead Minor slayer (5,0% damage done) did not affect the tooltips directly and it was calculated when dealing damage. So basically if your ability had a tooltip of 1,000 it looked something like this:
1,000 * (1+ CP) * (1+ DmgD)
Where
- CP means, for example Elemental expert (10,0% = 0,1)
- DmgD means "damage done", for example Minor slayer (5,0% = 0,05) or Minor berserk (8,0% = 0,08)
But now on Morrowind ZOS changed how Minor slayer behaves. Now it affects your tooltip directly. Meaning:
1,000 * (1 + CP + MSlayer) * (1 + DmgD)
Where
- MSlayer means "Minor slayer" (5,0% = 0,05)
So what does it mean? If we have a skill that has a default tooltip of 1,000, we have 49 points in Elemental expert (11,1% ~ 11,0%), we have a Minor berserk (8,0%) buff and we use 3 pieces of Moondancer (5,0%) jewelry. If nothing would have changed we got:
1,000 * (1 + 0,11) * (1 + 0,05 + 0,08) = ~1,254
Because of the change we now get:
1,000 * (1 + 0,11 + 0,05) * (1 + 0,08) = ~1,252
So the difference is minimal. But if we use this same example with a skill that has a % damage increase on its own (Puncturing sweep, Impale, ...) we can see a much larger difference:
1,000 * (1 + 0,11) * (1 + 1,4 + 0,05 + 0,08) = ~2,808 (Homestead)
1,000 * (1 + 0,11 + 0,05) * (1+ 1,4 + 0,08) = ~2,876 (Morrowind)
Where
- 1,4x (140,0%) is from Puncturing sweep's tooltip
So the difference is actually noticable (2,4% more in this case).
Now we can see that the more % damage increases we had the "less" Minor slayer actually affected (this has been discussed here on the forums many times so I'm not going to bring it up as detailed anymore). Now only thing that matters is how much CP you have; the more you have the "less" Minor slayer gives you.
Haven't tested is Major slayer working like this as well so can't say anything about it. It makes sense it would but you never know.
But how is it bugged then?
Like mentioned earlier Minor slayer affects directly your tooltip now. And it doesn't matter where you are (in an instance or not) the tooltip is always affected by it but the damage is not. So the tooltip your skill shows is wrong when you're not in an any instance and you have Minor slayer buff on. So not a game breaking bug, but still annoying.
