player.addperk 00101076 (extra damage 6)
I delved a bit deeper in this "damage" thing
just adding that perk like i did at first didnt help much
But what helped getting those damages is this.
type help "extra damage" 4 with quotes
you will see PERK extra damage , PERK extra damage 2 , 3 4 5 6 etc.
Make a note of those id's.
Now to what i did.
I started with player.addperk "id of extra damage"
I checked weapon stat
Then i did player.addperk "id of extra damage 2"
I checked weapon stat ( it should be a higher damage shown on weapon, and in the area under that window you also see damage, which will dramatically change).
I did player.addperk "id of extra damage 3"
I checked weapon stat ( it should be now a lot more damage shown).
I added up to player.addperk "extra damage 6"
With other words extra damage, extra damage 2, 3, 4, 5, 6, in that order.
So whats important that you start with player.addperk "extra damage" as first
Then do the other addperks.
The fact that you wont see those high damages in the big weapon stat window is, because i think 999 damage shown there is max,
it wont show any higher then that there, but in the area where damage is shown under that window you will see the increased damage is above 999 max.
to remove those perk id's and perks of which you made a note earlier, just use player.removeperk "id of extra damages"
Which should put weapon damages again to what they were
All and all playing around with those perks, should give insight in what works best for everyone.
