Enemy Melting Disc Thrower

Simply, place a bunch of Brine Fields, get close to enemies (inside the Brine Field), and hold down the trigger on the Disc Thrower. In detail. Hold down the trigger and aim for the Weapon. That is usually it, though sometimes on bosses I'd still right click to activate the secondary because you might not always hit the critical spot on bosses which would normally activate the secondary automatically. For the Ability, in any encounter, especially boss fights, place the Brine Field on yourself as many times as it takes until you only have one left. This could take 2 placements or 10 depending on how nice Freebie is. Every time you place it, it will reset the timer on it, and increase the radius and benefits it has by 20%. Then after that place it again every 10 second to keep it active, which is nicely a little longer than it takes to change once, so you don't have to count, just place it when you get it back, and keep it at one left. When ever the Brine Field is active, it will spread Blood to any enemy inside, and depending on how many you get to place, the radius can be as big as the whole encounter causing Bleed on everything. On normal enemies, this will usually cause you to get increase health when you kill them quickly. On bosses, it will execute them when they get low on health and make Frost work twice as fast on killing them.

Fan = Fast application of Gold and Frost, melting all enemies while giving infinite ammo. Freebie = A lot of Brine Fields, increasing radius, and giving more benefits per placement of the Brine Field, which you will be doing a lot of.

Gold is for your adds and crystals. Once you get a little bit into a dive, it will eventually instantly kill all adds by turning them into Gold. This will also give you gold, which depending on how much gold you will have (thousands if you don't spend too much), it will; increase you Gold damage, increase the chance of "gold execution" to almost always, increase your fire rate, and increase your damage resistance greatly. Having Gold on Primary with Halting Discs spreads the gold everywhere killing everything. Frost is for the bosses. When a boss is frozen, Frost will take away up to 10% of its current health away per second, along with up to 20% of its current health when it unfreezes. Mixing this with the Brine Field will then make the damage change to 10% of current health to every half a second. Blood is for when the boss gets low on health. When the boss is high on health, 10% if that is quite a lot, but when its health, gets low, 10% of low health does hardly any damage. That's when Blood will just execute the Boss and you move on.
