Bruh Lol I'm not gonna lecture you onto how Alchemy works, higher DPS than an abyss? are you on drugs? the Abyss Cylinder's main purpose IS water cannon.. comparing the tetra to a damage cylinder is something an Amatuer would do an Abyss has a 36% flat water alchemy boost while a Tetra has a flat 30% doesn't go ANY higher than that so to say that tetra would have Alchemy DPS over Abyss when it comes to water cannon is probably the most stupidest thing I've ever heard, even someone who doesn't even do alchemy could figure that out zzz but anyways back to what I originally came for is to help this person with his alchemy and what you would need is a cressida set with at least a water cannon enhancement but could take awhile since pieces are rare to find but to help maximize your water alchemy damage is to also try to get your hands on a professer J 2nd title if you don't have that already and the highest water alch title is Royal Alchemist title being that you should be qualified or if not a Royal Alchemist then you have that set already and for your gloves I mean it wouldn't really increase your damage but make your cloud more efficient I would get cloud range reforge on your gloves.
Well as for a stand point, you would want to max out your entire MP slot, DON'T enchant Magical or anything MP based onto your alchemy gear because MP is easy to max out. Once you do that just try to get a good abyss cylinder and do not use the Tetra for damage. It is a ultilty cylinder lol as in its for rain casting,Hydra,Frozen blast and other support alch skills but not for damage but anyways for water cannon reforge wise you wanna roll a water alchemic damage reforge since it is stronger than water cannon max but hey if you roll a dual reforge that's even better.
