my (and just about everyones) juicing process
get a map to 5 mods>put any that have a certain threshold of rarity+monsters aside (i usually do 80+)>chaotic rarity/monsters everything else>any with an open PREFIX set aside>get the rest to 6 mods>descrate all maps (you could also SINISTRAL necromancy+desecrate the non open prefix ones once they get to 6)>unveil the desecrates>Liquid emotion
The prefix unveil priority is
Over run>abyssal mobs have an additional modifier
those are easily top 2, after that its a matter of preference, while targetting rare mobs/rarity
i prefer
Rewards>depths>whatever else may give rare mobs/rarity
For suffix
Marked for death is really good, the rest suck imo ESPECIALLY the one where you don't deal damage 30% of the time.
for tablets
imo, i prefer a balanced map. So if my map is 100% rarity/20% monsters, ill use 3x rare monster tablets. I try to make them pretty close. MAYBE ill use a 10% quantity tablet
Make sure the map is always irridated+breached
