~Problem

Can someone please tell me how to defeat D'Sparil, the final boss in 
the registered version of Heretic?  I have pumped an unbelievable 
amount of ammunition into him and tried getting the Disciples to 
kill him, but nothing has worked.  Did Raven simply make him too 
difficult to defeat?  I hate solving all of a game except for the 
last level.  It screws up the whole experience.


~Answer 1

He actually takes less ammo to kill than a Maulotar - he's just more
agile.  I killed him on the 3rd try or so, and one time after he 
killed me, I saw him get killed by a disciple.

The time I killed him, I went through 2 invincibility rings (I 
brought one with me into the level, and there's another in a secret 
room in the level) while flaming him up close with a powered up 
Phoenix rod, then trashed him from a distance with Phoenix missiles.  
I didn't need help from a disciple.

Actually beating D'Sparil is very easy if you have a few things.
       
       1.TWO tomes of power, both of which are on this level
       2.Near full Dragon Claw ammo
       3.Near full Ethereal Crossbow ammo

Now all you do to beat D'Sparil is turn on your tome and roast him 
with Claw shots on his lizard from medium range so you can easily 
dodge his fireballs. After taking out the lizard(you should be out of 
claw ammo at this time too, if not keep using it) keep tome activated 
and keep hitting him. I find the crossbow w/ tome works best. You can 
tell if he is hurting when he starts to teleport away alot. BTW this 
is done on Heretics Ultra-Violence equivalent level and works all the 
time(for me at least).
