It seams that people are saying that their are now penalty's for stacking mods, I know about the recent shield recharge penalty, but did not know about any others.

Could someone please provide a link or list what the penalty's are for which mods, so we can all know about them.

Thank you, this should help us all out.

Also, it should say which mods have stacking penalties in the game.

Stacking penalties are not the same thing as the shield extender penalty.

The shield extender penalty is a flat +3% to depleted shield recharge delay per shield extender mod fitted. This is akin to the armor plate penalty, which decreases speed by a static amount based on the tier of armor plate you equipped. It goes STD/ADV/PRO=2%/3%/5%

Stacking penalties are a dynamically increasing set of reductions that increase in strength on a per module basis. If the mod is effected by stacking penalties, it will say so in the module's description. It goes:
First mod: 100%
Second mod: 87%
Third mod: 57%


After that, I don't know the numbers, just suffice to say that the fourth module is too low to be considered effective.

This seams to be for EVE and who knows if it translates to Dust.

Does anyone know what the Dust penalty's are for sure?

Those numbers have been experimentally verified to be the same for DUST.

I'd like to say Ben Hurin did the work on it (he's the work on 95% of everything else), but don't quote me on that.

I'm going to agree they have been verified. I haven't done "extensive" work on it but every module I've tested has conformed to the same stacking penalties as EVE.

So to recap for everyone.

If a module says their is a stacking penalty then it is as follows:
First mod: 100%
Second mod: 87%
Third mod: 57%

In addition there are but not cumulative, penalty's for armor and shields.

Any one disagree? of is this it?

Everyone else agree?

Profiency counts as the first mod
