Southperry's own Thief Flaunting thread =D

Also, that same skill boosts the shadow partner damage from half of the original damage to 65% of the original damage.

This really really looks like a mistake >_> I mean 130% first hit, 65% SP... except that the 130% applies to SP already, so you end up with 84.5% SP.

From 150% (SP) to 214.5% (SP+ds) = 43% damage boost.
