Dragon said:
Amduscias prefers to fight in wolf form; his movement rate is 18”, and he attacks with two raking foreclaws and his jaws, or his hind claws and tail. If in a position to do so, he can use all six of these attacks in a round, against as many targets. The claws do 3-12 damage each, the jaws 1-20, and the tail 1-10 constriction damage per round plus additional damage if Amduscias uses it to immerse a held victim in water, batter a victim against a rock, etc. The tail will loosen its grip if it is severed, or if it is dealt 17 points of damage in any single round or 26 points of damage over a succession of rounds.
Improved grab and constrict? Rake?
Bleeding Wounds (Ex): A wound from a Amduscias's gore attack continues to bleed after the injury was inflicted. Each wound bleeds for 1 point of damage per round thereafter. Multiple gore wounds result in cumulative bleeding loss (two wounds deal 2 points of damage per round, and so on). The bleeding can be stopped only by a successful DC 15 Heal check or the application of any cure spell or other healing spell (heal, mass heal, and so on).
Regeneration (Ex): Good weapons, and spells and effects with the good descriptor, deal normal damage to ARCH. If ARCH loses a limb or body part, the lost portion regrows in 1d6 minutes. ARCH can reaattach the severed member instantly by holding it to the stump.
See in Darkness (Su): All baatezu can see perfectly in darkness of any kind, even that created by a deeper darkness spell.
Spell-Like Abilities: (Caster level Xth)
At will—discern lies, dispel magic, faerie fire, fire shield (either version), locate object, produce flame, pyrotechnics, read magic, see invisibility, telekinesis (5,000 g.p. maximum weight, DC X);
1/day—symbol of stunning (DC X).
And of course we'll add some of the common SLAs for unique devils.
we need to figure out how to convert the whole "gp weight" thing from 1E. you missed this part: "Amduscias can cause fear (save vs. spell to avoid) in anyone within 3” he points at (but only one target per round)." since just about all of these guys have some sort of fear power, i wonder if this is an SLA or Su.
Summon Baatezu (Sp): Once per day, Amduscias can attempt to summon 1d3 abishai (of any color) with a 70% chance of success. This ability is the equivalent of a Xth-level spell (CL Xth).
Tongues (Su): Amduscias can speak with any creature that has a language, as though using a tongues spell (caster level Xth). This ability is always active.
Unnatural Aura (Su): Animals, whether wild or domesticated, can sense the unnatural presence of Amduscias at a distance of 30 feet. They do not willingly approach nearer than that and panic if forced to do so; they remain panicked as long as they are within that range.
