cyberdemon stats?

[Yqatuba]

I was thinking of making Pathfinder stats for a cyberd(a)emon like on Doom. I figure it should be pretty powerful like CR 19 but I'm not sure if it would be a demon or Daemon (the name seems to fit the nomenclature of daemons more.) Anyway I figure it would either personify death by technology (if a daemon) or be created from mad scientists and the like (if a demon). What do yu think?

Start with a daemon or demon and add some cybertech implants such as a cybernetic arm with implanted weaponry and a frenzy chip.

Don't forget to adjust the CR for additional equipment.

If I was to do this, I'd find an appropriate CR Critter and then just reflavor (and maybe change out, but that is more complex) spell like abilities to be 'demonic cyber weapons'.

So we look at the Olethrodeamon (CR 20).

It has the following Spell-like abilities

Constant—air walk, true seeing, unholy aura (DC 25)

At will—greater teleport (self plus 50 lbs. objects only), telekinesis, wall of fire, wall of ice

3/day—quickened disintegrate (DC 23), wall of force

1/day—blasphemy (DC 24), summon (level 9 any 1 CR 19 or lower daemon, 100%), wail of the banshee (DC 26)

I'd leave the constant ones alone, although maybe it would be 'cyber eyes' or similar things. Greater teleport i'd leave alone too. Telekinesis is a pretty good combat spell, but is hard to 'theme up' so I might trade that out for Lightning Arc. Wall of Fire/Ice I'd keep, just 'gadget them up' along with disintegrate and wall of force. The blasphemy and summon i'd keep as just 'demon powers'. Wail of the Banshee I'd either 'cyber up' or trade for something of equal power.

In any eveny, just because something is 'cybered up' and appears equipment based and with different special effects, it would still be magical and treated as a spell like ability in all ways. If this was a major theme of the campaign I might make up some rules for salvaging demonic cyber-weapons (including probably some special way to power it), and consider that part of the wealth gained with the encounter but if it was a one-off encounter I'd just let the characters know that they wouldn't be able to salvage the items.

Doing it this way is a lot faster than trying to add complex equipment that will change the CR of a creature.

For alternate abilities:

• Contagion so it can give people a 'virus'. While they're infected, any technology they attempt to use has a 50% to fail (this is a curse effect).
  
• Summon swarm to summon a plague of 'bugs'. Anyone nauseated should have also have technology fail. The bugs should be metallic, and have electricity vulnerability.
  
• Firewall or wall of fire that deals both electrical and fire damage.
  
• Once per day Blue Screen of Death, similar to entropic shield, as a screen it can place along one edge of its space (can erect, disable, or change sides as a swift action). Grants 20%–50% deflection against attacks from that side and natural or non-reach melee attacks subject the attacker to finger of death (but it's electrical damage) and shorts out technological items.
