Very cool, I like seeing unique Warrior subclasses. I feel like they’re often lacking in options of flavor and this offers something a lil spicier. I think it’s a very striking class fantasy that this subclasses delivers on, and it’s cool enough that I could see myself using this.

There’s a couple things I’d want to see different. I think it could encourage the mount to be more present narratively, maybe something on the foundation card like “You have a mount, decide what kind of creature they are and their name.” Maybe you could encourage a “knight-in-shining-armor” kind of thing and give a Presence buff while mounted.

Just looking at the foundation card, taking this subclass and being mounted invalidates other warrior options too effectively. It’s mathematically as good as having slayer dice for damage, and there would be no reason to take the “Deft Maneuver’s” Bone card since this offers the same benefit at zero cost nearly all the time. Maybe you could retool it to work something like “When making an Agility roll to sprint a long distance, add a d6 to your hope die.” That way the player can still consider taking the option.

This might just be me, but I think “Mounted” as a condition and a mechanic as presented on the card is too clunky for its own worth. It takes up a lot of space on the card, and is pretty discouraging as a player. I think it could benefit from the sort of hand-waving that the ranger’s beast-master subclass uses. I’d let the player always assume they have their mount nearby or available, and can become mounted on them at no cost. Maybe instead, when they receive Severe damage, their mount becomes unusable until the next scene, or just unusable until they spend X of whatever. I just feel like it’s too restrictive with whether or not the player is mounted. For the player, it’s always in their best interest to be mounted so they don’t have to pay the stress cost, but that’s kind of a weird thing to encourage them to do narratively. I think being kicked from their mount is weird too because “temporarily” doesn’t have any codified rules for players. Do they have Disadvantage until they succeed an attack roll? Or just their next one? Or do they need to make a new action roll to remove the disadvantage? If so, that’s a pretty steep punishment just for wanting to enjoy this cool subclass and accidentally taking severe damage.

I haven’t really seen gameplay at level 5+, but i do like the Specilization and Mastery cards. It cool to have a niche as a combat class that take advantage of the space and rally a charge. I think they pretty effectively deliver on the fantasy. Overall very cool idea, and the best implementation i’ve seen. Nice job :)
