NOt sure. Though I do currently have 4 trials flagged lol.
Anyways one sorta easy (well faster) way to do spiders if you have to solo and you have blm or at least rdm/blm. Check weather in the tree. If there is weather goign to be there go. Even go a day early. Gather together like 7-9 spiders. Keep full buffs (stoneskin blink phalanx pro) up eat taco for help though not necessary. If you want to be cute let them all hit you and get cursed lol (when they uncurse they go to like 89% hp). Then start againg them down and sleepga them. Once you get into the rythm you can often do it without losing a single buff. Sometimes you get resist and such so you can wake one early with drain then overwrite sleepga with 2 if on blm. Then just keep them all at <10% till weather pops. Immediatey kill them all gather another group fast get them somewhat down. If weather still up burn 2hr get anoter 5-9. Much better than killing 1-2 then watching weather depop on the 3rd kill
