Inventor of Super-Toast
All-around vision?Their bodies are circled with glowihg red pinprick-eyes that look in all directions simultaneously.
How's this?They speak no language of their own and do norrespond in any way to a speak with dead spell. They seem to communicate with each other on some instinctive level to coordmate attacks in pack formations, though this is non-verbal in nature. They understand orders given in the commoa tongue or drow, and can be commanded by those with the ability to command or control undead.
wraith-spiders are affected only by silver weapons or magical weapons.
DR 5/magic or silver for both spider and web?Like the wrath-spiders themselves, the webs cannot be cut by normal weapons; they can be cut only by silver or magical edged weapons, or broken by a successful bend bars/lift gates roll.
Do we want to have a special create spawn if the victim is an arachnid? Perhaps their energy drain can bestow undeath upon spiders only?However, since they do not always turn victims into more wraith-spiders (though there is speculation on what happens if anormal or giant spider is killed by them), they are sometimes encountered alone as attrition takes its toll.
