All of 's three currently playable characters have some pretty excellent Rail build potential, but none is quite as satisfying as Vermillion's capacity for critical damage.
One of his two SyComs, Gunslinger, guarantees that any hit following a critical hit will also be critical, allowing him to do massive burst damage with the right loadout.
Not only is Gunslinger's ability pretty excellent, the base stats it gives are nothing to sneeze at, giving this SyCom high potential in most runs.
When it comes to your Breaker's loadout, there are a lot of things to consider. For one, there are tons of Rail, Blade, AMP, and Holobyte options to pick from, so how are you to choose?
Additionally, you have to be aware of how much durability your weapon has, and if you're not going to make it out of your current run alive, how will your build change when your Holobytes depreciate?
