Nyssian Choker

I have always loved the choker creature, as it seems to be the most typical dungeon creeper: looking for food and scraps of treasure, never overly dangerous, but something that fits into the underground lurker theme so well. But I dislike their small size and bare intelligence, Mine is adjusted for levels and size, you can scale the HD to use them not just as threats for the lowest levels. Good stand alone protector, willing to hide until the time is right to strike.

Treasure Value Half Standard

Advancement Typically Monster / HD or rogue levels

Appear identical to the standard creature, but increases to a medium size at 4 HD. They are also much smarter then typical chokers found on many other worlds. This doesn't mean their primary tactics are vastly different but they do have an escape route ready if the attack fails. They are anti-social, preferring to be left alone to do their work, guarding small areas, either in dungeons or locations next to them.

Unlike their kin, they often work for others, as part of lair defenses to protect an area. they kill weaker creatures and capture others so they can be questioned. They follow simple orders, as they have problems with anything too complex. Stories abound over city revolutions, where one group is deposed and another coming into power, and they still don't even know where the choker guards or their safe words to get through dangerous passageways protected by these critters.

HD Advancement Table

4 HD +6 skills, Feat, Increase to Medium Size, +1 natural AC, Increase Dmg (1d6+3)*

5 HD +6 skills, Increase Tentacle Dmg (1d6+Double Strength Dmg)

6 HD. +2/+2 to any 2 Ability Scores, +6 skills, Feat, +1 natural AC

7 HD +6 skills, Increase Tentacle Dmg (1d8+Double Strength Dmg)

8 HD Gain +2/+2 to any 2 Ability Scores, +6 skills, Feat, +1 natural AC

9 HD +6 skills, Increase Tentacle Dmg (1d10+Triple Strength Dmg), +1 natural AC

+HD Natural AC increase every other HD, +6 skills, Increase choking multiplier dmg every +3 HD

Monster HD increase is the most typical route for advancement but the rare few will gain rogue levels. Once they take non-HD levels they are unable to gain additional Monster HD.

*Only one tentacle does maximum damage, the other is one damage level down. Normally if the first attack is successful that one inflicts max damage. If the second one hits, it does the higher damage capacity.
