Skateboarding Rules for B/X

I've been getting into skateboarding again recently, I used to do it a lot as a kid but then I moved to where the closest sidewalk was a mile away in town.
Anyways here are some rules for movement on skateboards.

Characters

All classes gain a new save, save vs wipeout. This is used to avoid the consequences of board based acrobatics and other tricky maneuvers. Dexterity provides a bonus to wipeout saves as Wisdom provides saves vs magical effects.

Level Cleric Fighter Magic User Thief Dwarf* Elf Hobbit

*dwarves gain a +2 bonus to avoid wiping out on downhills due to their mountainous upbringing.

Vehicles

Boards are defined by their 3 speeds, their Flat Speed, Wobbling Speed, and Max Speed.

  • Flat Speed is how fast the board can go on flat ground at normal cruising pace. This speed may be maintained as long as the rider wishes on flat ground
  • Wobbling Speed is the speed at which some control of the board is needed. A save vs wipeout is needed to do any tricky maneuvers while moving at wobbling speed.
  • Max speed is the maxium speed a board can handle before the death wobbles set in. Moving above this speed requires a save vs wipeout every round to stay on the board.

Skateboards (10gp)

FS (45') WS (75') MS (100')

Longboards (15gp)

FS (60') WS (85') MS (110') Special: Tricks are impossible on the longboard.

Movement

A skater can accelerate by their encounter movement per combat round.
While going up and down hill this acceleration is changed depending on the four categories of slope.

  • Slight: 5'
  • Notable: 10'
  • Steep: 20' (not accelerating once the skater has hit Wobbling Speed is a tricky maneuver)
  • Suicidal: 30' (the skater has no choice but to accelerate)

While moving uphill this value is subtracted from the skater's acceleration, while moving downhill it is added.

Additionally while going downhill encumbrance factors into acceleration. The difference between the skater's unencumbered speed and their current speed is added to their downhill acceleration value. For example a skater so encumbered as to be moving at 10' per round instead of the default 40' would gain a +30' acceleration per round going downhill.

Wiping Out

Wiping out on non solid ground is just treated as falling. Wiping out on solid ground the skater suffers 1d6 damage per 10' of speed they had while wiping out.

Combat

Attacking someone while traveling at 60' per round counts as a mounted charge.

Mask 01: Mask of the Iron Warriors

  Hello, welcome to a strange thing I am attempting to start. The great magic mask relay. It begins with one person describing a magical mask, it can be for any length and for any setting they wish, it can even have mechanical implications if the writer desires.  Once they have written this, they are going to tag (be polite, ask them if they are fine being tagged in) another person to write a magic mask and this chain continues until 100 masks have been described. They make sure to link to the blogpost you were tagged in and then once the person after you had made their post link to theirs. The blog posts should be formatted as Mask #: Mask Name. That’s pretty much all the rules, make sure the person you tag reads the rules.  EDIT: 11/17/2025. You have probably been linked here by a blog that doesn't follow the rules above, bully them in the comments about it.

I made a 120 Room Dungeon in a Month

So I run an open table D&D game for a youth center. I got myself a notion that I had two months before I was gonna be running a game so I might as well try doing some daily dungeon keying and by the time I had to run a game then I’d have something sizable to run for the folks at the youth center, an d I could keep expanding it until I had a full megadungeon to one day release. I started brainstorming and decided on a general outline of the dungeon I came to this general premise The Burrow: heavily overgrown complex that while technically underground is only so by a foot or two of topsoil and has enough cave ins that natural light isn't unheard of ????: more standard dungeon, no strong theme but heavy aesthetic contrast with the barrows above with darkness and no greenery. The Grand Ossuary: massive catacomb complex teeming with undead. The caves of prehistory: like cavemen and shit can be found here, decidedly natural as opposed to the two prior levels, heavy focus on ...

Nithhugyr

 Back when man ate the planet the nithhugry was made. On command they would hollow out entire mountainsides, now only a few are left, roaming the places few dare to tread. They appear in swarms of 3d100, combined into a singular worm. Each segment is 15’ long and 10’ wide Nithhugyr: HD 2+12 per Segment, Atk 1 Bite (1d12+6) per 5 Segments, AC as Chain + Shield, MV 60' or 40' Burrow, ML 11. Swallow: If a bite attack beats succeeds by 10 or more, the target must save vs Wands or be swallowed whole. If swallowed whole the victim travels down the body at a rate of 1 segment per round, suffering 1d6 damage per segment. If not swallowed whole the victim is hanging on for dear life in the mouth and must make Strength check each round to hold on. Succeeding by 2+ allows for escape, failing by 2+ means swallowing. Break Apart: If a segment is destroyed the swarm becomes two independent worms., Heat Vent: Has a 1-in-12 chance each round to release jets of searing hot air, scalding ...
