Speedrunner:
The speedrunner is a character who tries to do things as quickly as possible. Abilities are as follows:
* Accelerated movement: The Speedrunner gets the same movement speed as a monk.
* Wall clip: The Speedrunner can move through a wall by getting enough speed. To do this, the character must start and end the move on a valid square, and the wall must not be thicker than one square on the grid.
* Item use glitch: The speedrunner, by using this ability, can equip or use any item. If equipping, the item can be equipped in any slot (so, for example, one could equip a full plate on the head, or a long sword on the body.)
* Duplicate item: At will, the speedrunner can create a duplicate of an item, provided they have some other item in their inventory.
* Icarian jump: This ability allows the speedrunner to boost their Acrobatics skill by 1,000 points for one round. One can then use this ability to perform really high and long jumps, if they can succeed at the appropriate skill check..(This allows a long jump of around 1,000 feet, according to the rules.) This ability may be used 3 times.
* Wrong warp: On going through a door, the speedrunner can choose to end up anywhere else in the game universe.
* Credits warp: On reaching 19th level, the game's credits trigger.
* Arbitrary Code Execution: At 20th level, the player gains the ability to get the game to execute arbitrary code. (In the table-top game, this ability gives the player all the abilities that the GM has, including the ability to change the rules and apply Rule Zero.)
