Did a little bit of testing last night with engulfing flames, burning embers, and molten whip- just watching base damage and crits.
I tried: (all purples cause I didn't have yellow nirnhoned)
Nirnhoned
Sharpened
Precise
With apprentice mundus
As well as:
Nirnhoned
Sharpened
Precise
With mage mundus
Basically:
Nirnhoned > sharpened > precise
Mage > Apprentice
Sharpened & Nirnhoned = not giving stated amount of spell pen
UPDATE:Focus Rating Values: without any buffs up, same bars and gear for all, apprentice mundusI'm using Harven's Extended Stats, not sure if this is reliable information or if another add on would be able to provide me with better info.
Forgive me if I'm wrong but shouldn't the sharpened value be 12% higher than the no staff value? And shouldn't nirnhoned give 4% more than sharpened? If this is how it is intended to work, and this add on is correct, both of these traits are broken.
No Staff Equipped 16422
Sharpened Staff Equipped 16542 (purple) -supposed to give 12% increase to spell penetration, should be 18393. A loss of 1851 spell pen. It's also curious that when equipping a yellow sharpened staff the value does not change at all. It remains 16542.
Nirnhoned Staff Equipped 16560 (purple) -supposed to give 16% increase to spell penetration, should be 19050. A loss of 2490 spell pen.

But if the character sheet is correct, the difference between nirnhoned & sharpened is very slight. It's only a difference of 18 spell pen. This difference certainly doesn't amount to 4%.
Also, what is everyone's focus rating at? I feel mine is low but I'd like to know what the avg is.
UPDATE:
Damage numbers vs. Scaled Court Conjurer. Flames of Obv up, full pvp buffs, 50% crit chance (except with precise, 57%)

It seems to me that both sharpened and nirnhoned are underperforming in terms of actually applying the correct % increase of spell penetration. Nirnhoned gives more than sharpened but both seem to be weaker than they should be. If anyone is more knowledgeable about the relationship between spell penetration & spell resistance, please feel free to share. I'm by no means an expert but my basic math and understanding of this concept tell me that 1) nirnhoned needs a buff, it does not provide 4% more spell pen than sharpened. 2) neither provide their stated % increase of spell pen
