For anyone unaware - Bloodthirst is a morph of the skill Flurry, located on the Dual Wield skill line as the first skill you can acquire.
The base flurry is a channeled attack, hitting 4 times. Bloodthirst morph means you heal for a percentage of the damage dealt.

Firstly:
1. If you look at your character sheet, the Major Sorcery/Brutality DO SHOW on the numbers when activated - they directly alter the number on your sheet when active.
2. When you look at the damage the ability causes before and after activating it, you will see the damage go up because it shows how it is affected.
3. You can do the same test by looking at how much damage your skill would do when Wrathful Strikes is not slotted, then look at it after you slot Wrathful Strikes.

Medium Armor passives (assuming you are referring to Agility passive which boosts weapon damage) will be added into the value of your weapon damage on your sheet.

So, basically, everything you listed in the description is visible on the sheet, except for the Champions Point slottable, Wrathful Strikes, which would be the one you might consider a 'hidden' ability, yet the effects of it are shown when you mouseover the Bloodthirst ability.

No need to wonder, you can actually see it very clearly with almost no effort on your part by slotting, then un-slotting, the CP.

I think they meant bloodthirsty the jewelry trait. Which would be harder to test and I wouldn't mind hearing a definitive answer on either.

Hmm, so you're saying the question is:

In which order are bonuses applied. Is it multiplication then additive or additive then multiplication.

Best way to test would probably be equip triple bloodthirsty at 180 a piece (no glyphs)
Then switch in 174 infused rings (so the discrepancy is only 18. Next, equip something worth 18 (a lower levelled helm's 1 set bonus would work) so you get equal numbers.

Test on a dummy to see max weapon damage - if they both give the same numbers, you know it works. If they offer different numbers by around 112, you know it doesn't.
Same for wrathful - equip wrathful versus equipping a flat bonus of equal value.

Thanks for comments. I found here on forum that in 2020 when bloodthirsty trait was buffed to 350 dmg, there was notification it is done because bloodthirst doesn't benefit from sorcery/brutality. Looks like this rule still works and infused trait in my case is better than bloodthirst one.
