There's several great spots I found for my BST (71) to solo. Probably many more for my level and around it as well.
Can also be done in Bhaflau Thickets
Pet: Tigers / spiders. (all DC mobs)
Target: Tigers / Spiders. (all DC mobs)
Respawn: 2min after death.
This form of exping was mainly for the farming aspect. Tiger pets are great against spiders, and vice versa. Was getting 60-67 exp per kill. Spider Webs dropped maybe 1-4 every hour as BST/WHM. If I was /THF, would probably drop a lot more often considering how many you can kill quickly.
I don't really remember much for this one. There are DC bats in near the entrance from Wajaom Woodlands. Near them are Even Match - Tough crawlers. Further in, you'll find Tough - VT trolls. Used EM Crawlers vs a PLD Troll. Gave me about 160exp with pet still charmed. You'd need to do some investigating of your own to find out more. Not a bad area, would have stuck around longer if not for a 72 BST exping near the entrance, and a duo PT killing the crawlers and trolls.
Looking at the Wajaom Woodlands map on ffxi-atlas.com, enter the Aydeewa Subterrane zone through mark "8".
Pet: Slime Mold (or whatever those 2 slime type mobs are called right by the entrance). Checked Decent Challenge everytime to 71.
Target: Qiqirin Archeologist (Tough-Very Tough @71), no aggro but links to sight, ranger type mob. 2 close together by the zone, several others spread out.
They gave me 220-260+ exp without exp ring. One slime is enough to take out a VT as long as you fight alongside it. The biggest problem with this however is that the slimes are EXTREMELY HARD to charm. We're talking 1/4 likely at best a successful charm. And this is with an Apollo's Staff. Mess up the initial Charm and you may have to zone it. Dealing with the Qiqirin's habit of running away is something you can't really do. There's a good chance they'll run into a link. But most of them are ranger type mobs, so they're fairly easy to handle even if a link happens. Just need to know what to do... which I won't share, since this is the type of stuff that makes players better. This area is mainly recommended for those who aren't afraid of mischarm, aggravating death (for you), and constant need of zoning. As well as the well equipped, since you'll need all the help you can get to charm the slimes.
Hope this helps some people because it was giving me hell trying to find areas for my BST to exp in. IC was getting really annoying.
