Looking for the pvp build - mantra burst
That’s generally the build. You don’t take chronomancer for this one trick pony. Instead you’ll usually take chaos for PU so that you can get a bit more mileage out of MI and torch. You could alternatively take illusions (for a bit more might sustain and crit) or inspiration (for actual sustain). You’ll also usually use fire + air on the greatsword to maximize the instant burst damage.
