75k Culvert Cont4+Ror4 Swap Night Walker - Maplestory Reboot [Kronos]

New rotation using cont swap into ror, big thanks to ray and raz for the tech on equipping cont outside to line up the timing exactly where you want it by entering with x time left on the 2min debuff (in this case attack at 15s on debuff to proc fatal and enter at 14s) This gives me cont for the Rapid Throw at 97s.
There was a big jump in culvert score too by saving rapid throw for after stage 6 but to achieve this i delayed rapid throw and every other timing by a couple of seconds so buffs are popped 3s early instead of 5s early. This was because buffs were expiring before the 7s rapid throw finished if i didn't get any extension on buffs.
