uhmm homie to capture something you need to keep attacking it until it starts to run away with a limp in its step. then pitfall or shock trap it and use 2-3 tranqbombs on it and it will be captured, longswrods get unlocked around 3 star village quests.
and skid, i used rathian+ armour because it has good stats, like health increases and hearing increases. queropeco porbably isnt the best bet if your a blademaster. cuz its defense is really bad.
