There's not special order to do the quest, just request for ALL the missions before starting and deliver them ALL after finished, that way there wouldn't be missed points.
The whole task:
Need to be done with at least 4 150+ players or 3 lvl 200+ using summons otherwise doesn't compensates time nor supplies.
Charting, ordnance and measurements In eastern cave, lure and trap lava lurkers (use parcels to close the ways as the white lines in the map), then use Gnome Chart and Trignometre on their marked Spots ( 5 measure spots X mark, 3 charting spots star mark, these items can be obtained near the NPC), careful with damage spot ( skull mark), finally escort gnomes (5 needed) from their spot to the entrance.
In order to get Bonus points from ordnance is needed to gather 3 magma crawler (the pink line is the parcel that need to be removed when gathering magma crawlers, trap until all team arrive).
Charting could be delivered but u need 3 extra spots for bonus, the other 2 end here.
Estimated Time: 10-15m (generally would be needed to gnomes to respawn).
Diremaws/Home/Subterraneans/1+spot charting; In Southern cave, diremaws task require using pesticide into a diremaw corpse (20 needed per player, no bonus) which also have a possibility to spawn 1 diremaw, home task require killing 20 lost exile, if they are close to a makeshift house (green circle with a check mark) they wouldn't count, also "using" the rubbish of a destroyed house have a chance to spawn a captured dwarf which could be escorted to the entrance (3 of them are needed for bonus home bonus point), subterranean task require killing 50 diremaws/deepworms, this task and Diremaws could be finished into the last spot (northern one). Finally, there is one charting spot behind the regular cave, use chart there (Purple Circle on Image).
Estimated TIme: 15-20m. 5/10 extra min if doing charting bonus.
Explosive Growth and Finishing Charting/Diremaws+Subs In Northen cave, here there are deepworms/diremaws, subs/diremaws task could be finished here, in order to obtain explosive growth point is needed to "pull" explosive barrel to each spot (3 spots minimun), 2 of those spots are also spots for charting, since is needed to deal with a considerable ammount of diremaws/deepworms all through the cave this is the task that take most ammount of time, since doesn't provide too many points is easily skipable which reduce considerably the difficulty of the task.
Estimated TIme: 30-45m.
Total TIme: 1h-1h 30m.
Now how works:
-Charting 1 point for 3 locations in eastern cave + 1 extra (2 locations from northern cave 1 location from southern cave)
-Measurements 1 point for 5 locations in eastern cave
-Ordnance 1 point for scorting gnomes 1 point for Magma Crawlers
-Subs 1 point from 50 kills (deepworms+diremaws) southern/northern cave
-Diremaws 1 point from 20 pesticide uses (require 20 dead body diremaw per player) southern/northern cave.
-home 1 point for 20 kills of lost exile +1 point for 3 captured dwarfs. southern cave.
-Explosive Growth 1 point for 3 spots +1 extra for all 5 spots, northern cave.
So Explosive task and charting bonus could be skipped saving up to 1h and then a huge team wouldn't be needed, the other tasks could be easily done in 20-30m daily and only 3 points would be missed.
Easiest path:
Charting (without bonus),
Ordnance (depending on the server maybe ppl wouldn't let you get bonus from crawlers),
Measurements,
Diremaws,
Subterraneans,
Home (doing bonus takes longer).
Lvl: 100-150, solo, Time: 30-45m at max (15 min luring/trapping lavas and doing gnome tasks, 15-30m doing dwarves+scouts task)
Points/jar: 3-4 from gnomes, 1 from scouts, 2-3 from dwarves = 6-8 jars daily.
Doing it with 1-2 friends 150 reduce considerably the ammount of time spent but isn't enough to do extra tasks.
