The quill mechanics encourage fast attacks in order to activate them. So perhaps the argent peacemaker and sentenza for gunners. I believe the autogun may fire too fast to activate all the quills before the charge or attack is done. For swords, flourish line/btb, obviously. Not sure about bombs, whether the haze bombs can trigger quills with the pulsing status wave effect.

With the cloak, I'm not exactly sure how it would benefit bombers, other than losing aggro and retreating. But that's applicable to any playstyle. For swords, considering you rely on regular attacks coming out of stealth, heavy hitting weapons like the 2 hit combos should work well. It gives a small window of opportunity to take that slow swing into their backside, before they detect and turn. The large knockback on the second hit should create a good area of safety for you to do, well, anything. In most cases, gunners stay at a distance, although the same concept for swords would apply. Maybe you like to get into large mobs and kite inside them. Alchemers would be suited for this, using the same concept as the swords. Sneak in, unload asap. The antigua lines would not be as useful for this considering that they require multiple bullets in the clip to hit.

The hexing haze... I don't have it, but from what I've seen it looks like a 3* haze bomb radius. Tag enemies, enemies go boom. In essence, a delayed aoe with the possibility of hitting more targets. I suppose its just another bomb for bombers. Nothing really special about this one until the ultimate. The status condition seems to be iffy. Most people would just carry a haze bomb of the status they want. The haunted haze which makes each killed monster howlitzer seems like the better choice. I feel like that this would benefit the swordies and gunners more, specifically the ones that focus on taking down a small amount of monsters at a time. This lets the ghosts soften up the group before the knight approaches them. Bombs tend to be area focused damage, so most monsters will fall within 1-2 charges, more if they aren't of the same type. I doubt the damage from the hex would be as much as a bomb, so it doesn't seem as useful for bombers when the enemy is about to die in the next hit.
