Use the lightning spell to knock out the blue crystals in the three eyes shooting the
lightning out. They power Bonegrinder so as many times as you hit him, you won't kill him.
After you knock out the crystals, though, you can easily kill him with any of the high
damage or AP weapons.
EXTRA HINT : There are no health elixirs or life potions prior to him or before him when
you are in the lava room and you have to kill a lot before you get to him. Make sure you
have reserve health elixir and potions in your pack.

In game play press L1 R2 L2 R1 in order.
While holding those buttons press x,down,triangle,up,circle,right,square and left.You will
be invincible and you can beat bonegrinder easily

Where is bone grinder? Is he next to the tornado or something?

OKAY YOU HAVE NO IDEA IM A CHICK AND THERE ARE POTIONS AN INVISIBILITY ONE AT THAT

These are some weird answers i'm readin' and hearin'.
When the battle between you and bonegrinder starts,he will be invincible but if u take out
the blue crystals in the statues,he won't be anymore.To take out the crystals,use the bow
u got from the treasure chest(if ur skill for bow is 2) or use attack spells(I would use
the fireball one).I would stay away from boney before taking those crystals out(if ur
using the invincibility cheat,then no need).

it is great

To kill bonegrinder use an attack spell or a bow ( attck spells work better ) and knock
out all three crystals in the eyes, after you do that it will b mucheasier to kill him.

EXTRA HINT: To the right when you enter the place Bonegrinder is, there is a lever and a
transporter. Pull the lever to activate the transporter. After you knock out one crystal
from an eye, if you are low on health, step on the transporter and it will take you back
to the entrance to the entire lair, so that you have time to boost your health, you can
return through the transporter to finish him off.

once you have killed him pick up his sword and find the platform with a lever. then pull
it and step on the platform you will be transported outside where it is nice and sunny !
:D
