Sibriexes are fiends—demons, to be specific—but there’s also something distinctly aberration-like about them. Partly, it’s their Lovecraftian body-horror appearance; partly, the fact that they move only by floating; and partly, the fact that their mere presence is toxic to living things.
Their ability contour is bizarre: extraordinary Constitution and mental abilities alongside merely average Strength and almost nonexistent Dexterity. From this we can conclude that they’re heavily dependent on magic and make no effort to avoid attacks—“psychic brutes,” if you will. We’ve seen this before in one other monster: the githzerai. Githzerai, however, are highly mobile. The sibriex is a slow-moving juggernaut.
Despite their extraordinary Wisdom and Charisma, sibriexes don’t have much reason to stay and chat, nor do they have proficiency in any social skill that suggests what kind of conversation they might engage in. Therefore, I’d say, a sibriex that weighs the odds and finds itself outmatched simply never bothers to engage. The upshot of this is that a sibriex encounter should always be Deadly (see “Encounter Difficulty,” Dungeon Master’s Guide, page 82); throw in a handful of minions if you need to. When it does engage, it uses its telepathy to tell the player characters what it’s going to do to them, in nasty, dripping detail. Continue reading Demon Tactics: Sibriexes
A couple of months ago, a reader noted that I’d analyzed liches but not “their degraded selves,” demiliches. I have to confess, I’ve been putting it off, because analyzing liches was a lot of work. Fortunately, demiliches don’t have such a large repertoire of spells to analyze, so that reduces the complexity.
Demiliches have the same compulsion—the will to power and immortality—as liches, but unless they’ve shed their bodies willingly, there’s an additional element to their character: frustration. They’ve forgotten to feed their phylacteries, or they’ve been prevented somehow from doing so. As a result, the immortality they worked so hard to attain has cheapened. They’ve lost their sense of purpose and their ability to cast spells. They may even have forgotten that they can regain their physicality by feeding new souls to their phylacteries. If reminded of this fact, they’ll forget every other concern and fixate on restoring themselves to lichdom. (Strangely, neither the demilich’s stat block nor its flavor text explains how a soul is fed to its phylactery. Seems like kind of an important omission.) As long as this memory is lost to them, however, they’ll act with malice, tinged with the occasional random miscalculation that stress produces.
Aside from the lack of spellcasting, a demilich differs from a lich in the following ways: Continue reading Undead Tactics: Demiliches
