These guys are... weird. Turn schizoid? Opens its wings to turn metallic? Elizabethan ruff?
SPECIAL DEFENSES: Cannot be confused; surprises on a 1-3
PSIONIC ABILITY: 170/170
Attack/Defense modes: C + Psychic Pandemonium (detailed below), F, G, H
PSYCHIC PANDEMONIUM: This psionic attack mode attacks exactly like a Mind Thrust, but it may only be defended against with Tower of Iron Will, and then takes double pts. from the defender.
A mapmaker’s primary attack is accomplished by spreading its wings. This causes its entire body to turn metallic and glow with darting, scintillating colors. Any creature within 12” viewing the mapmaker in this state must make a saving throw vs. paralyzation a -2 on the die. Creatures getting a 4 or less on the die (before modification) turn schizoid until a Heal, Restoration, Limited wish or Wish is used. The paralyzation lasts for the number on the die plus 5 rounds.
NOTE: Magical devices will not negate or prevent this effect.
The sucker mouth extends out 2”, and the tail is barbed. The mapmaker will try to use its tail to draw prey to its mouth (it can drag prey a distance of 5 feet on a “to hit” roll of 18 or more).
Hits on the mapmaker’s ruff do half damage, while hits on the hump do 1½ times normal damage. Mapmakers’ ruffs scintillate harmlessly when removed from the body; they are very strong and might be worth something to a jeweler or cobbler.
Mapmakers have their own language, and all their maps are written in it.
Mapmakers love to steal a party’s map so the party will be lost. When stealing maps, the creatures’ senses are heightened and they have 8th-level Thief abilities.
A new magic item is included with this monster: the Mapmaker’s stick (it can mark anything, including human flesh; thus, the 1-4 damage pts.)
Immunity to confusion and insanity? Improved Init as bonus feat, and possible racial bonus on Hide/Move Silently?
Scintillating pattern would probably suffice in this case, but if we want to stick with paralysis/insanity rather than unconsciousness/stunning/confusion, we can do so.
This seems to imply extended reach with its tail. We could follow the roper/cave fisher/bonespear drag approach, or simplify it to improved grab with tail, then free bite against grappled foe. I think I'd prefer the latter.
I'd recommend giving them telepathy, common to most outsiders, so they can communicate with others. This would still preserve the difficulty in reading their language.
At the very least, they should get good ranks and maybe a racial bonus in Sleight of Hand. I could see giving them uncanny dodge and/or evasion as well.
So would this weapon require a touch attack?
