Fast Striker + Heavy Swing Perks?

[Tex]

So I'm trying to not spend perk points willy nilly and make smart choices with them, however I'm curious about how these two perks in particular stack with each other.

Fast Strike makes my attacks do 20% less damage but cost 30% less stamina, while Heavy Swing makes my attacks do 20% more damage but cost 10% more stamina. With this in mind, will I essentially get a 20% stamina reduction on attacks if I take both of these perks, or do they not stack that way?

Thanks to anyone who can offer some assistance!

So if I am not mistaken
Fast Strike is only for weapons that use Agility (like short swords, sabers etc)
Heavy Swing is only for weapons that use Strength (Longswords etc)

So they do not work together, it depends which weapon you have equipped that will decide which perk you have active.

Nev is right.
Mutually exclusive.
That being said Heavy Swing is vastly superior for Stamina is no problem later on anyway.

From what I'm remembering on reading them this is correct. Also I think it says they're mutually exclusive.

Ah I missed the text that said it was weapon dependant. Thank you gentlemen for the assistance!

Confirmed. Also, with enough play, you are likely to get enough skill points to cover it, I think.
