It's probably better to just take one lashwhip and a set of scytals (Chuckles if you can't make an extremely abrasive criticism of my wording of this as I made 100% sure that it is correct--it's clown-proof
). This would give you the extra attack and take away enemy attacks. Probably still better to stick with 2 sets of scytals though unless you know you will be up against high attack, few in number guys with powerfists (maybe one of those decked out vanguard vet squads you will never see, more likely it would be something like GK termies though).
