Unlocked yes. What happens is that in the 3 sets of gear you see at the start, any unlocked stuff goes into the random pool of what you’ll get (once you unlock the random giving of gear). In addition this applies everywhere else throughout the entire game. So in the beginning it’s totally fine, as you’ll often get what you need. Later on, once you’ve unlocked a heap of stuff it all gets a bit annoying as you get what you want FAR less.
What I’d recommend is only unlocking the good stuff and not put cells into the rest. What’s good? Well there in lies the challenge in working out. ESPECIALLY if your attempting to play the game blind to all the guides online.
What I’d recommend:
Melee Weapon - Twin Daggers or Frantic Sword. Both do some damn fine DPS. I prefer the Twin Daggers of the two as you crit on every 3rd hit in a combo, where as the Frantic Sword only crits if your below 50% health.
Bow - Ice Bow - Every site I’ve read said that this weapon is crap, but I COMPLETELY disagree. It negates the need for the ice grenade entirely and makes every battle A LOT easier. The boss battles in particular are an absolute breeze with this in use.
Skill Items / Grenades - Aura of Laceration as this does some decent damage. Ice or Flame grenade upgraded to level 2 to get the 20% damage reduction (at level 5).
I’d also HIGHLY recommend getting the general categories blueprint from Graveyard which will make getting exactly what you want from a vendor MUCH easier.
As for turrets I like the ceiling turrets most as they never get attacked by enemies. On boss battles though it’s not so useful compared to some of the others. For general use though, it’s great.
