Ebon Tiger (GEP)

__TOC__
Those who've seen these elusive beasts describe them as "great cats wholly composed of black fire." Ebon tigers' shadowy bodies give them a 100% chance to hide in shadows on prime-material worlds, where they prefer to hunt for "real" meat. Their insubstantial and virtually weightless bodies (even on the Prime) grant ebon tigers immunity from normal weapons, allow them to move silently, and give them the ability to pass through holes or cracks with ease. The ebon tiger accomplishes such feats by constantly keeping the bulk of its body on the Border. Thus, even when "material," an ebon tiger is also "ethereal," so it's able to sense and interact both with Border and Prime features (and threats) simultaneously! If in extreme danger, an ebon tiger can shift itself fully onto one plane or the other once every 24 hours. (MYSTARA MONSTROUS COMPENDIUM Appendix)
