I don't think I can do better than that. At least, not going by the video. Really, all I can glean from that is that he's good with a sword and pistol.
Can critique stunts, though.
-1 Charge Attack (Weapons) - When you perform an attack, you may accept a -1 penalty to your Weapons skill before you roll the dice. If you do, a successful attack applies the fragile aspect "Staggered" in addition to any stress dealt.
This seems worryingly powerful.
-1 Pistol Stun (Guns) - Add +2 to your Guns skill when Maneuvering to place the aspect "Staggered".
I think it would be better to take a stunt letting him wield that pistol with Weapons. This is one of those cases where optimizing makes the sheet feel more natural, if you ask me.
-1 Visceral Attack (Weapons) - When you tag or invoke an aspect named "Staggered" to aid an attack, add 2 stress to the result when successful (in addition to the other benefits). Then the "Staggered" aspect fades.
-1 Trick Weapon (Weapons) - You tuck your straight sword into a large cumbersome sheath transforming it into a dull, two-handed broadsword. Your broadsword attacks with Weapon:4.
There probably shouldn't stack, at least not fully. That being said, I wouldn't blink if you wanted to make the sword weapon 3 normally.
-1 Old Hunter Bone (Lore) - You may Maneuver using Lore to place the aspect "Quickening" on yourself. This aspect can be tagged to gain +1 to your dodge rolls for the rest of the scene. Additionally, it allows you to move 1 zone as a supplemental action when you dodge.
I can't say I like this maneuver-with-special-rules set-up. There's gotta be a better way to stat this kind of ability.
Also, I don't think taking supplemental actions in response to attacks works very well.
-1 Beast Roar (Lore) - You may Maneuver using Lore to place the aspect "Knocked Back". You may tag this aspect to move a single target 1 zone away from you.
Feels weak. You can already make maneuvers, you shouldn't need a stunt to move people with KNOCKED BACK.
Also, this doesn't really feel like a mortal stunt.
-3 Bag of tricks - 12 potion slots.
Old Hunter Bone - A Block:6 or Armor:3 against attacks, 3 uses per session (3 slots).
A Call Beyond - A zone-wide Weapon:5 attack, 3 use per session (4 slots). Aim with Lore.
Call of Ebrietas - A 6-shift Maneuver to place the aspects "Staggered" and "Knocked Back", 3 uses per session (3 slots).
Messenger's Gift - A Block:5 versus perception, 3 uses per session (2 slots). Transforms the Hunter into a part of his or her surroundings.
Bag of Tricks doesn't work this way. It doesn't let you spend multiple slots on an item. Also, you can only spend 1 Refresh on more items.
Ritual (Crafting) and a Refinement will give you a similar amount of power, though. And it'll let you spend stress for extra uses.
