I'm going to be the coolest gunner around. :P
I'm using two guns (no swords and bombs. duh?) for my character. I'm currently using the Autogun line (normal dmg) and the Magnus line (piercing dmg), but I'm still doubting if I go that way since some say the Autogun series is not ideal for full-time gunners (It's rapid shot isn't ideal for the Gunslinger gears, and it has normal dmg also which isn't ideal for full-time gunners).
I'm planning to have two guns with contrasting powers, each with different uses. What is the best combination? I want suggestions from veteran gunners. :(
If you're only going with 2 gun slots get two alchemers. One should be elemental and one should be shadow. At higher levels their bounce can really add up the damage. This should give you a nice coverage of elements and you won't even be doing grey damage plus you still have all your movement.
I chose the alchemer that has can apply freeze since it doesn't cause enemies to go crazy like some status efects.
If you buy a 3rd weapon slot, I would use the Magnus then. Magnus is a good gun, but be careful while using it as it leaves you very very open.
As a gunner, you need to capitalize on enemy weaknesses or you won't be doing enough damage.
