Omg an inner ability to raise a speed level????
DO. WANT.

And uhm what? Amount of enemies hit +1?
Blast hitting two mobs? What?

Don't think that applies to blast. Else hurricane would be hitting 2 mobs as well.

I know this becomes useless with Tempest, but I'm going to ask anyway. Does this calculate the stated % of one stat and add it to the other with no penalty to the former stat, or does this actually transfer the stated % of the former stat to the other?

i.e.Is it...

A. Character has LUK -> DEX 10% and 4 DEX 600 LUK. Final result: 64 DEX 600 LUK

OR

B. Character has LUK -> DEX 10% and 4 DEX 600 LUK. Final result: 64 DEX 540 LUK

Also, does it use the base stat or the total stat? My guess is the former.

How about this? Is Shield Mastery applied to this at all? If it is, Paladins will benefit the most from this.

No penalty.

Not sure about the Shield mastery query.
