Added a customsettings.lua file to the mod (usually found at steamapps_workshop_content_322330_764204839)
Within you can change the formula for the health. I looks like this:

function(NumPlayer,OnePlayerValue,SixPlayerValue,prefab,name)
return OnePlayerValue + (NumPlayer-1)*((SixPlayerValue-OnePlayerValue)/5)
end

-- this is the formula I currently use. you can replace this with whatever you like
-- NumPlayer is the number of players currently on the server
-- OnePlayerValue and SixPlayerValue are based on the modsetting. On Quicksetting="normal" they will be equal to DSValue and DSTValue you can see in the valuelist in modmain.lua
-- prefab and name are for advanced functions, see my prefabslist in modmain.lua to see prefab=name pairs.

Added spider_healer and spider_dropper, both {200,400}.
Added "Very Hard" modsetting (DST 1 player and 2times DST for 6 players).

- Improved the code to save maxhealth of mobs (needed to have correct current health after loading). Now it only saves the maxhealth of mobs of this mod, not the player or other things.
-> compatible to Level mod.

Added Grassgator {500,1000}

Added:
Worm={450, 900}

and sorted the detailed list of mobs in modsettings alphabetically.

Added:
Celestial_Champion1={2000,10000},Celestial_Champion2={2600,13000},Celestial_Champion3={2800,14000}

The higher "unload" health will have the same ratio.
