Paired with my Excalibur Umbra Build here: https://overframe.gg/build/233066/
This build just lets you swoosh through everything in the game. Star Chart, Steel Path, you name it, it's already cut in half by the time you're doing saying the name.
Both Sacrificial mods because you have the free slots for them, and they're lovely mods to have.
[Chromatic Blade] will give you guaranteed status procs if your [Excalibur]'s ability strength is over 200%, resulting in over 100% status on your exalted blade. We're using Viral on the weapon with Primed Fever Strike and North Wind. We could use the 60/60 mods, but we already have 100% Status Chance, so I prefer the higher damage.
Because of these guaranteed Status Procs, and because we cannot put [Blood Rush] on this weapon, we run both [Condition Overload] and [Healing Return]. Tons of damage on top of what is basically Lifesteal? Yes please. Your [Excalibur] is never going to die, while cutting through enemies like butter.
