Underrated weapon. 5 forma seems expensive but this thing can delete SP enemies with ease without even using the incarnon mode.
Heat status can be proc on the initial charge of the incarnon mode, meaning a group of enemies will have you hitting the 480% damage of Cascadia Flare before you hit the big boom at max charge.
Galv shot increases your status change and gives a modest boost to damage to the base fire.
faction mode double dips on the dots, but you really don't need it. You can easily replace it with gun slinger or [Anemic Agility] for similar performance and faster charge rate of the incarnon shots.
you can drop a 6th forma into it to get an exilus, and if you do [Ruinous Extension] is the go to. You could even go insane and get this thing 7 forma to get [Lethal Momentum] instead if you prefer the base shot to be more hit scan.
overall, INCREDIBLY strong weapon. I'd recommend it. and this is coming from a [Lex] incarnon main.
