Tested Krin's to see if it is a display error or if it is truly not applying properly. Test would not be possible without the help of Interstellar Marine, thank you for being my guinea pig.

Test #1

Test #1 was using a 'Guardwire' Bolt Pistol on a AmAssault with no damage mods shooting a CalAssault with 707 shield. First trial was to test the BP with no damage mods at all. Shot reduced shield to 500 HP, thus dealing 207 damage. Shot a second time to confirm. Next was to switch to a AmAssault with 3 stacked Krin's. Shot reduced shield to 480, dealing 227 damage. A second shot was taken to confirm. 3 Krin's provided about 9.6% more damage (227 / 207) than with no damage mods by my math.

Results: Krin's is working for sidearms. May be applying less damage than it should, I ask someone with more knowledge of stacking penalties to confirm my results.

Test #2

Test #2 was using a 'Templar' Scrambler Rifle on a AmAssault with no damage mods shooting a CalAssault with 707 shield. A fully charged shot was used to ensure accurate results. 1st trial was with no damage mods. Shot reduced shield from 707 to 333 for 374 damage. A second shot was taken to confirm. 2nd Trial was with 3 stacked Krin's on a AmAssault. Shot reduced shield from 707 to 296 for 411 damage. 3 Krin's provided a 9.8% increase in damage by my math (411 / 374)

Results: Krin's is working for Light weapons. I ask someone with better knowledge of stacking penalties to calculate if it is providing the proper bonus.

Test #3

Test #3 was using a forge gun on a friendly Sica I called in using a 'Strumborne' Forge Gun on a sentinel gk.0. Only one shot was taken to prevent getting booted from FW. No krin's reduced Sica shield from 2200 to 1076 for 1124 damage. 2 Krin's decreased Sica shield from 2200 to 991 for 1209 damage. Krin's provided about 7.5% extra damage over no mods (1209 / 1124)

Results: Krin's is applying properly. I ask someone with more knowledge of stacking penalties to confirm my results.

Conclusion

Krin's is applying extra damage to both sidearm, light, and heavy weaponry. It appears to only be a display error in the fitting screen. It feels like I should see a bigger difference in damage between no Krin's and 3 Krin's, so perhaps it isn't applying fully. In any case, I provide the data gathered in a spreadsheet below for all to see.

I have a favor to ask.
Could you run the exact same test, but switch out one of the Krin's with a Light Damage Mod(preferably Complex)?
And then run another test with just 2 Krin's?

I want to see how the stacking penalty transfers from one mod to a different type of mod.
I'm curious if the Light Damage mod also applies a penalty to the sidearm damage part of the Krin's.

I only tested to see if Krin's was working or not. I still think it isn't giving me the full bonus, or maybe I'm bad a math. Any case, further testing will require waiting til after the weekend and a new guinea pig.

Based on the numbers you showed us, the stacking penalties seem to be working correctly when you just use Krin's.

No I meant whether they correctly implemented stacking penalties for normal damage mods plus the Krin's together

[edit] that is to say, the text says *any* mod that affects the same stat. will incur the penalty. But I believe this is standard EVE text and not sure there has been any modules up to now that actually do this.

Now I think about it, I could probably put the HEPs next to some kincats on a suit and see if that changes anything. But the suit readouts for damage is bugged so can't tell in-game for damage mods.

Oh, interesting. There's still the problem of PROTO AV one shotting HAV's though, which is really odd, because it shouldn't.

According to the stacking penalty calculator 3 Krin's should be giving a 10.08% bonus. This is very close to what happens in game. Is it possible that Krin's is giving a lower bonus, or could my own proficiencies and augmented ammo facility leading to the small discrepancy

EDIT: In addition, I will be testing hoe Krin's interacts with sidearm, light, and heavy damage mods on Tuesday to see if there is a problem there. Any volunteers to be my guinea pig?

Im willing to be a guinea pig, i log in on weekends, jus let me know.
