Health - 1,394,500 (Normal) / 4,183,000 (Heroic)
Mana - 234,190 (Normal) / ? (Heroic)

The fight takes place in a lush, oasis like valley inside Ulduar. There are three Elder boss-tree mobs you can choose to kill or not, appearantly they are similiar to Sartharion's hard mode if you choose not to kill them the fight gets considerably harder as each elder buffs Freya and her adds.

Elder Brightleaf - The essence of Elder Brightleaf increases Magic damage dealt by Freya and her Allies of Nature by 50%.
Elder Ironbranch - The essence of Elder Stonebark increases physical damage dealt by Freya by 50%.
Elder Stonebark - The essence of Elder Ironbranch increases Physical damage dealt by Allies of Nature by 50%.

As you engage Freya, she will spawn multiple adds and start healing herself. She starts the fight with 150 stacks of a buff increasing healing on her by 4% (=600% at the beginning of the fight), a stack is removed everytime one of the add she spawns is killed.

Abilities
Freya 4,183,000HP (25-Man) / 1,394,500HP (10-Man)

Nature's Fury - Infects an enemy for 10 sec, causing it to inflict 4625 to 5375 Nature damage to its nearby allies every 1 sec. (10-Man: 2035 to 2365 damage)
Sunbeam -- Inflicts 10638 to 12362 Nature damage to enemies within 8 yards of the target. 1.5 cast. (10-Man: 7863 to 9137 damage)
Touch of Eonar -- The presence of the Lifebinder heals Freya for 24000 health every 1 sec. (10-Man: 6000 health every 1 sec.)
Attuned to Nature (x150) - Increases healing received by 4%.
Photosynthesis -- The rays of the sun heals the plant life for 10000 damage every 1 sec. (These will spawn during the fight, make sure you kite the adds out of them to prevent them from healing)

During the fight she will also spawns 3 extra adds at the same time (Storm Lasher, Stone Lasher, Ancient Water Elemental), they have roughly 1M HP each and you have to kill them all 3 at the same time, otherwise they will just revive. Killing one of these adds will remove 10 stacks of healing from Freya.

She will also spawn a bigger add at some point, an Ancient Protector with 1,9M HP. Just off-tank him and kill him to remove 25 stacks from Freya.

When Freya finally runs out of "Attuned to Nature" stacks, just start DPSing her while you keep killing the tree adds she spawns (they will heal her for 15% after 10 seconds if you don't kill them). Lower her life to 0 and she will become friendly again, loot the chest next to her for tons of epic loot!

sounds easy enough, thanks seren!
