Tree of life

Populate 1, necromancy 1, destruction 1,
knowledge 1, lifesteal, green 2, white 2, black 2,
red 2, blue 2.
The tree of life protect her humans. Summoning
zombies to protect them, shooting needles to flying
enemies, giving them knowledge and giving fertility to
the ground. Her roots suck the life out of the
decomposing enemies as she provides energy to her
citizen. Too bad she burns so well.
