OK, I'm sort of new to this, so feel free to edit, because I want to get as good as I can at this, as fast as I can.

Well, you will be needing the following:

Water mark

10-15 bone pillars

6 chryssoras (jelly fish poisonous things)

6 bone walls

6 poisons

other options:

6 sparks (to give fuel to the bone wall)

a few water pillars and ice bolts (in case of those annoying otyughs)

and an arsenic (hard to get, so it's not mandatory, but it is a great add, even better with an animate weapon)

Strategy (without options):

play your bone pillars and jelly fish things pronto, then bone wall (if your more defensive, you might play bone walls sooner, your choice), and stack the poison; its pretty straight forward. If you add the listed options or different things I didn't list, kudos to you and good luck making your own ownage strategy.
