Is your feature request related to a problem?

1. Rain of arrow of saturation, do not drop all the arrow instantly, it drops batch by batch, so CoC trigger rate should be higher than current calculation
2. DD of chain will explode corpse in a chain if there is a corpse. Current calculation only calculate damage for single corpse.

Describe the solution you'd like

1. Rain of arrow of saturation should have a trigger rate multipler calculated based on time window of each arrow batch and time window of CoC cooldown/server tick
2. DD of chain should have 3 dps calculations mode. single corpse, 8 corpses, single target. 8corpses mode just x8 dps of single corpse mode. Single target mode should calculate how many corpses a setup create per second then compare with maximum corpses consume per second, take the min then time with dps per single explosion.
   Calcalate corpses per second can be archive by using trigger rate of desecrate and unearth with number of unearth projectiles

The issue does not name files or tests. Start by tracing the existing DPS calculations for Rain of Arrows of Saturation, Cast on Critical Strike cooldowns, and Detonate Dead of Chain; done means implementing and validating the requested arrow-batch trigger multiplier and the three corpse-consumption calculation modes.
