Windows

What is the value from the calculation in-game?

In game displays a reduction of enemy chaos resistance of -42%

What is the value from the calculation in Path of Building?

In pob the calculation shows -41% chaos resistance

How to reproduce the issue

1. New pob
2. Add despair curse
3. Add essence drain or a wand with chaos bolt to observe pobs resistance calculation.
4. Modify curse magnitude so that theoretical calculation would have a trialing decimal of ##.500 or higher.
5. Observe how PoB rounds this value down
6. In game will round this value upwards.

In my case, I have curse magnitude of +79%
And then less effect from blasphemy of 46%
Level 12(11+1) despair curse base of -43% chaos resistance.

The theoretical calculation is simple as shown in the curse effect mod calculation screenshot.
-43 * 1.79 * .54 = 41.5638
In game this gets rounded to nearest whole (up) of 42%, in pob this gets rounded down to 41%.

I picked up and dropped a couple 6% curse nodes on my tree to further observe in game behavior and found that with a theoretically calculated value with a trailing decimal of less than ##.500 it gets rounded downwards in both pob and in game.

discrepancy exists with enfeeble as well

Base is 25% less enemy damage.
(I picked up a 6% node for testing)
Calculation is 25 * 1.85 *.54 = 24.975

In game is rounded up to 25%.
Pob rounds down to 24%.

I'm taking the values displayed under enemy health bars as gospel.. I dont know if it's just a visual bug in game, as in the amount applied in game is the rounded down figure but visually it's rounded to nearest whole?

[rwZIFb7N]

to be clear in game calculation matches PoB when the calculation lands on a final value of #.000 up to (not inclusive) ##.500

Meaning that in game end calculation appears to get rounded to nearest whole number while PoB always rounds down.

If this discrepancy exists with despair / enfeeble I imagine it applies to all curses. but I haven't done that testing
