While farming Sanguine Hibiscus's I saw a hibiscus on another side of a broken bridge. There's a long way from the first boss to that spot, so I tried using rocketboots to jump all the way to the other side.
So with a group with rocket boots you can skip the second boss and most of the trash between first and last boss with rocket boots, or if you're just solo farming Hibiscuses for Sporeggar rep you can skip the part where almost no hibiscuses spawn and jump to the last "room" (keep left) with 3 hibiscuses. Also, the Bog Lords (not the Bog Giants) have a huge aggro range for a lowlevel mob, distract it when it's close to entering last boss's room.

Rocketboots at the red line, jump at circle, you should land where the arrow is.
If you start seeing nagas, you've gone too far (there is a hibiscus spawnpoint at the last giant just before the bridge though), turn back abit, it's somewhere to the west after the first boss around the Bog Giants.
Once you've jumped, you can turn right for the boss with a pet, or go left for the last boss.
5 Hibiscuses gives 750 Sporeggar rep, one run gives around 9-12 and takes about 8-10 minutes. I made 161 in the first 15 resets, you might have to wait around 10-30 minutes after every 5 reset, you can keep running around for 10 min longer in each reset if you'd like since they keep spawning, but resetting and waiting 10-30 mins every hour is better imo since you can go afk and do other stuff.

If you need more screenshots or directions I'd be happy to provide. If this is a repost, I'm sorry for wasting your time (I searched for "sporeggar" and couldn't find anything)
Not sure if this is supposed to be an exploit or a trick (it's kind of both), please move to the correct forum if it's wrong.
