@Skrag:
If there was no penalty what would be the reason for NOT using it?
@luc
If you weigh the 5 penalty stages with the 5 peak stages.
You'd get (-120/-90)% (weapon/Spell) vs (+100/+100)%
And a nice weapon damage of oh 30. (Which is Ok for PvP)
That penalty stage would cost you 120% damage total or 36, or just about 1 hit wasted.
At the peak stage only you'd get a bonus 100% or 30 in this case.
So you would be at -6 at the end of it.
Lets say you wanted to maximize it and spent the last 5 hits executing a crushing blow
Your total damage bonus would be 45. which would be a + 9 bonus on every one of those 5 hits. And doesnt count the additional accumulating 28 damage you would have gotten from the incremental increase. So You sacrifice 36 damage and end up doing 73 damage. (or if you had used crushing on every single hit that was receiving a bonus ( as well about 86 damage.)
If you swing that over to pvm, where players achieve damage on a much larger scale you'll also have the option of armor ignore in your arsenal as well and you can put up larger numbers.
If you're talking magery numbers are more on the obvious side since you can get past the penalty with 5 magic arrows and trade the cost of those 5 ( 12) damage for the opportunity to do 5 flame strikes which do the damage of 6.(a 31 dmg bonus)
Of course if you're playing a bushido character where you invest maybe 3 mana for a huge hci bonus, constantly stacking damage up to 100%, and the chance for a free armor ignore every swing, focusing weapons are probably not gonna help you all that much.
As for artifacts since SA, if you cant find a powerful enough weapon, armour piece or jewel, you're probably not imbuing it right. The only thing introduced since SA more powerful than the capabilities of imbuing have been ship cannons and there's no way I'm making those hand held.
