Please correct me if I'm wrong, but currently the only way to get the Exobyte-Infused Escrima Sticks weapon style is by having points in the Dual Wield skill when you play the light house mission where you fight Bane, and selecting the appropriate weapon reward from your quest completion options. It's a quest reward, not a drop, so it can't be obtained later. There is also no other quest reward or drop in the game that offers this Dual Wield weapon style. Was this an oversight in design, or was this deliberate? It's really irksome that a player with no foreknowledge of this is essentially screwed out of this weapon style.
