About damage essences in Delubrum/Dalriada

[Fland]

What examples? I've seen some people say combining certain essences and lost actions can be even more of a boost, but I haven't seen any Math indicating it's more efficient to farm all of that stuff. How much time does 1 person using these actually save? How long does it take to farm all of the different components? Provide some approximate figures.

You using Elder will give you 50% damage increase, saving 1 minute from the run. Then you use Cure IV which will give AOE bravery to you and your party member. With bravery, everyone in your party including yourself save 12 seconds each from the run for a combined total of 96 seconds. With the initial 1 minute from the essence itself, you have saved a total of 2 minutes and 36 seconds from the run by yourself.
Farming cluster for 10 minutes for example can give you 10-20, so each fragment worth farming for around 30 seconds to one minute. Cure IV fragment can be obtained by killing level 1 bird which just take several seconds to kill.
See now? Elder + Cure IV is worth a minute of farm while saving you 2 minutes 36 seconds just by your contribution. Additionally, this is assuming using one fragment of Cure IV each run, but the reality is you can use Cure IV from one fragment for several DR runs.

This is just one example, there are others like Rend Armor which benefit the entire 24 people, or Seraph Strike which is persistent skill that you can use for the entirety of a relic run, saving even more time significantly all from one fragment worth 30 seconds to 1 minute of farm.
