Didn't have time to write a new post today, so instead have something I made a while ago for my RPG Tumblr!
The card prompt is Breakneck Rider // Neck Breaker, and it's a GLOG class.
Breakneck Rider // Neck Breaker
Starting equipment: Leather armor, a trained steed, a monstrous form
When you roll your starting stats, roll each one twice. Your mundane form has the higher of each mental stat and the lower of each physical one, while your monstrous form has the opposite.
Your GM chooses when you transform.
A: In your mundane form, when riding your steed, you ignore encumbrance when calculating speed. In your monstrous form, your unarmed attacks count as Medium weapons. (They do 1d6+Str damage, probably, but it depends on which GLOG you're playing.)
B: When you reduce a creature to 0 HP with a melee attack, you can deal excess damage to another creature within reach.
C: You can choose to transform once per day. You can also veto when your GM chooses to transform you.
D: In your monstrous form, you can kill and eat your steed to regain all of your HP. (You need to get a new trained steed to use this again.)
Additional notes
These notes weren't in my original tumblr post:
The nature of the monstrous form is intentionally left vague. On the card, it's a werewolf, but you can make up whatever you want.
"Your GM chooses when you transform" isn't meant to be a weird competitive thing between the player and GM. They should work together to determine a consistent set of rules about when a transition ought to occur. (Examples: time of day, phase of moon, emotional state, scent of blood, imbibing a specific drug...) Then, the GM should be in charge of refereeing those rules. Think of it like a warlock patron - even though the GM runs the patron and the player runs the warlock, and the two might be at odds, the ground rules were set collaboratively during character creation.
The veto the player gets when they earn template C isn't once per day. (I realized that wording was maybe ambiguous.) At any time they would transform, in either direction, they can choose not to.
I really like GLOG classes! They're short and sweet.
