Heat Build
Make [Chromatic Blade] heat and get gas + rad build, the reason why you want this is because rad, like electric status, arcs between enemies and gas creates big gas clouds. Both the arcs and gas clouds can inflict the status effects so it will create a mass spread from one enemy to the next constantly. Not only that, we have enough ability strength for [Chromatic Blade] to the point where we don't need to add any status mods and can focus on crit chance, dmg, and crit dmg. Plus the gas clouds will deal massive DoT because of the radiation procs adding up to +550% overall damage.
Cold Build
Make [Chromatic Blade] cold and get viral + rad build, the reason why you wanna do this is because rad status adds adds up to +550% overall dmg and viral status adds up to +325% dmg to health. Not only that, but the [Exalted Blade] has high slash procs so it will end up dealing massive bleed dmg(DoT) that ignores armor. Plus as mentioned in the heat guide we have enough ability strength for [Chromatic Blade] to the point where we don't need to add any status mods and can focus on crit chance, dmg, and crit dmg.
