BLM in Turn 6. Any pro tips?

3.) you can't aetherial manipulate out of briars so be sure to just be on the edge of them

I'm not a BLM, but are you sure you can't (as in, actually tested it, not just reading skill description)?

I ask because three DRG jumps (Dragonfire Dive, Spineshatter Dive and Jump) all can be used from in the Briars, despite the skill descriptions of "cannot be used when bound" (Elusive Jump's description says it can be used regardless of bindings); same for MNK's Shoulder Tackle. So I assume you can use Aetherial Manipulation from within Briars...which should help DPS
