Skills: 12 ranks
The original had Hide, Jump, Move Silently, Search, Spot
Skills: Xaver have a +8 racial bonus to Move Silently checks.
All around vision appeals. For skills: does Jump really make sense for these? Could we figure out something more appropriate (like say Climb)?
I'm in favor of dropping Jump and adding Climb.
I'm not too worried about backwards-compatibility with prior conversions (only with original source material).
Those skills seem alright to me.
If you want to do that...
Creature Catalogue said:Xaver are curious little creatures shaped like bladed weapons, that corrode metal in a similar manner to rust monsters. A xaver’s diet consists entirely of rust from ferrous metals and alloys, including iron, steel, mithral, and adamantine. They are more intelligent than rust monsters, and will not ignore a tasty meal like a suit of armor or pile of weapons for a mere snack like a handful of spikes or nails.
A xaver looks exactly like a sword, usually a short sword or longsword. Their hard, silvery bodies have a smooth metallic appearance to them, and are flat and tapered to a point on the upper end. The other end of the monster is bulbous and resembles the handle of a blade, which is set with six faceted green eyes that resemble tiny gems. The hilt-like end has 8-inch long retractable worm-like legs, set between each eye, on which the creature scuttles about, and can retract them with lightning speed to hide from danger. It has no senses of hearing or smell, but its eyes provide it with darkvision and normal vision. Xavers give off no body heat or sounds, and do not breathe in the same manner as most living creatures do, absorbing solar heat and gases through the bladelike part of its body.
Xavers prefer rocky, even mountainous lairs. Sometimes they lair in a large treasure hoard, such as that of a dragon, abandoning it when they have eaten all the digestible metal. They have no treasure of their own, but they are often found among treasure. They live for centuries, and can go for years on end without eating, so they are not aggressive hunters. Xavers are solitary by nature, but not territorial and never fight each other for any reason.
COMBAT
Xavers can lie motionless as other creatures approach, looking like an inert weapon, then attack when characters carrying lots of metal come near. They cut with their razor sharp edges, swinging their bodies in a series of wild, circular slashes that form a battle dance.
