Dehkia Cyclops Shai 90% holding RMB ~12k/18k Trash (2xLS)| Black Desert Online/BDO

Its more like 85-90% of the time holding RMB, depending on how fast you clear cyclops.
You have to recast RMB atleast every minute. That should not matter as you should rebuff also every minute anyway. You could do it more lazy without buffing.
With attack assist it aims your rmb to the closest enemy. During gargoyle phase you can only use rmb(with my gear atleast). It is no effecient grind, but lazy. You can easily watch something else.

For people more familar with shai like me, we can also grind gargoyle phase with our normal rotation without looking at the game, even without aim assist. If you really wanna grind like that, i would recommand crit rate addon and AP addon on RMB. I had -DP, but was too lazy to change it.
