Grove Guardians

Strategy:
The worst thing about this is that these three all spam the sapling sleep ability, especially the smaller two. The big one casts lots of stonega, drain and aspir. However, a Pld and a Whm can deal with the big one for a few minutes, leaving you 4 people to fight the smaller ones.

You can try poison potions. They definately help for certain people (mages) to have right off the bat. However, the plants have additional effect: poison with their attacks, so any melee engaged with the mob will find their poison potions wearing quickly when the additional effects wear off, making them more vulnerable to subsequent sleeps.

Probably the best configuration (besides 6X BST) is Bst x2, Pld, Whm, DD, DD. CourierCarrie used twice can tank the smaller ones down to 25% left. Note that these spalings cannot be charmed, nor slept. In this team you put a crab onto each of the smaller ones, and keep them away from the main fight. The other 4 of you kill the big one, and as soon as that is done finish off the smaller ones.

We beat this with Bst, Rng, Pld, Whm, Blm, Blm. We entered and had the bst call carrie and wait 5 mins for his timer to reset. Then buffs and Rng starts the fight with a barrage to one of the smaller ones. Pld vokes the big center and pulls him to the opposite side of the arena, the bst occupies the other smaller one with Carrie in the hallway. Whm keeps Pld alive while Blms help ranger to kill their fast. Bloody bolts are a must for this fight. I alternated between holy and bloody as I deemed necessary. When a blm got hate I recast utsusemi, but otherwise just took my lumps and used my bolts plus healing from the blms to stay alive.

After the first small one goes down, we had 1 blm to help whm heal. Yagudo drinks are obviously necessary. Meanwhile Rng Blm Bst took down the second small one.

With only the big one left it was simply a matter of having enough mana to heal the tank until the Rng could kill it. Technically we used benediction on our first win, and invincible and eagle eye on our second, but we wouldn't need any of it if we tried again. It got late and we postponed orbs for a future date.
