Black Vulmea
SOC-12
I'd go with a sharpened machete.
IIRC the survival kit in DA4 Marooned/Marooned Alone includes a machete; the description says to treat it as a Blade for combat purposes.Machete is always what I have thought.
The canon text suggests the Blade's more like a main-gauche, but since the machete is treated as equivalent, you could bring in similar blades such as a parang, a panga, or a facão Sorocabano - I've used the same stats for a kukri, frex. The only question is a skill one then: is Blade-1 the equivalent of Machete-1, and is the reverse true as well?
