1. Don't bite off more then you can chew.
If it looks like it can kill you it probably can. Avoid those Very Tough and Incredibly Tough mobs. This may not apply to BST more then other jobs.
Avoid those links. If you know they link and they are bunched together theres a good chance they will link.
2. Bring a reraise item.
Nouthing hurts more then dying in an isolated area with noone to raise you and having to Home Point. Losing all that EXP that you gained and then having to run back to where you were soloing sucks. If you see it comming and you are surrounded by aggro mobs die in a safe place where you know they won't aggro once you reraise.
3. Escape plan.
You know you are about to die and I hope you have an escape plan. Know where the zone is and how to get to it under pressure with a very angry mob on you're tail. If you don't mind running back to you're area bring a warp item. Better to warp out then lose the EXP you have gained.
