[Tecmos Deception]

Probably two SSOYs. 20 dex is probably ~1 extra proc with your mainhand every 5 minutes, and while the partisan does have a somewhat better ratio than the SSOY (and ratio in offhand is what determines both the damage and the threat, apart from procs), adding in the SSOY in your offhand will be giving you a bunch more aggro from the procs than the 20 dex and slightly better damage from the partisan will.
