Spells with 100% weapon damage

[CumeriTarenes]

I have a question about spells which make wapon damage.

Does self buffs which do more damage count in these spells?

I noticed today (after I changed to shortbow setup) that my recharged arrow does not influence the damage of dual shoot.

Is this how it is intended to be?


Edit: For lethal strike I know it adds the addidtional damage of recharged arrows.

Edit 2: correction, recharged arrows adds no additional damage to lethal strike. I was wrong there as Froste proofed in his post.
