A star vampire is a yet another Lovecraftian monster in SLASH'EM. It possesses six tentacle attacks, three of which can drain life.
The star vampire is the only monster besides the (master) mind flayer to have a tentacle attack. The message one sees when attacked is "The star vampire's tentacles suck you!" One should note that although this is the same message as the mind flayer, the star vampire does not eat your brain; its attacks merely do physical damage and possibly level drain. One should also note that, unlike the mind flayer, a ring of free action does not protect you against the star vampire's attacks, like it does protect against mind flayer attacks in SLASH'EM.
Due to their speed and high number of attacks, star vampires can dish out incredible amounts of physical damage. Because of this, one should always seek to destroy them alone if possible, and if surrounded, keep in mind they do respect Elbereth. Magic cancellation is a must to protect against their draining attacks, although this should not be a problem by the time one encounters them.
