Monstrous Monday: Ghost Spiders

I have been working on a set of game boards to depict Lolth's lair in the Abyss.  They are not done yet and hope to show them off soon.   I have been taking my family through the Classic Greyhawk Campaign starting with T1 (AND B1) and working all the way to Q1 Queen of the Demonweb Pits. 

While running I have added other material to the campaign to flesh it out more. This includes such classics as Bone Hill, Ravenloft, and Castle Amber but other details like a Stone Giant fortress Cloud Giant castle in the sky (for G4 and G5 respectively) as well as more details for the Drow City of Erelhei-Cinlu and a revamp of Lolth's lair.

While it is too late in the game for me to use it, Joesph Bloch, the Greyhawk Grognard, has released his own D4 to expand the Drown of Erelhei-Cinlu.  You can find it on his blog. 

It looks fantastic really, and let's be honest, Bloch knows his Greyhawk.  So I am certain that it would have been a nice addition to my campaign.  Plus it ties the GDQ series a little closer to the Temple of Elemental Evil, which is the ultimate goal of my campaign as well.  I understand he is doing a Q2 or something akin to that.  I have also wanted a good Q2. Though I am adapting the Monte cook adventure "Queen of Lies" for it.

But until then, I have a few more "spiderweb" monsters I need to weed out the uninspired choices in Q1. 

Here is one of them.

Ghost Spiders appear as semi-transparent, glowing ghosts of huge spiders.  They are not spiders, nor are they exactly undead, but rather they are the demonic projections of fears powered by necromantic forces.

A ghost spider is found anywhere where the influence of demons is strong and where mortal creatures can interact.  The fears of spiders are magnified till a ghost spider is created.  As such it radiates a fear aura that mimics the spell Cause Fear.  Anyone under 5 HD/Levels must make a saving throw vs Spells or fall under the influence of the spell-like effect.  Creatures higher than 5HD/Levels gain a +2 to their save. Creatures 9HD/levels or higher are immune to these fear effects.  Those affected will be frozen in fear and unable to move, run, or attack. The ghost spider will then attack with webs (as per a giant spider) to immobilize other potential victims.  Then will then use their bite to kill others.  Ghost Spiders are not living and therefore do not require to feed on victims. They instead feed on the fear they cause and the pain from deaths. 

Ghost spiders are treated as undead and can be turned as a 5HD creature or as a Spectre.  Like all undead they are immune to charm, hold and sleep spells. They can only be struck by magical weapons. Once destroyed the ghost spider will not reform, but other ghost spiders may be created in their place at a future date.  The only way to destroy them forever is to remove the demonic forces that create them.
