Yeah, he took Heavyset as a trait in the end.

A bit of background - as I've posted elsewhere, I've been running a game this week for some friends, running for 6+ hours a day  and I thought I'd post my thoughts so far.

The characters they're playing are a noble-born Coinshot who's being persecuted by the Inquisition for inventing something he shouldn't have, a Thug who (as a half-breed) wants revenge on his noble father for causing his mother's death, and two (!) Feruchemists - one the put-upon steward of the aformentioned Coinshot, and the other one who was driven completely mad when he failed to save his family from a burning village.

The things I've noticed so far, mechanics-wise, are that:

• Feruchemists are really powerful if you let them have too long to charge up - the best way of dealing with this being that they get cracked down on hard by the Inquisition if they "hulk out" in public.
• Pewter is much better than most other Mistings in combat because it adds to your roll instead of replacing it - while Pewter is the "combat metal", it seems a little off that the Coinshot gets a dice pool of 6 and the Thug gets a pool of 11 as starting characters[/li
  
  • Having a good Physique doesn't seem to help with Steelpushing - you can't make a really buff Coinshot and win Pushing contests just by being heavier. In fact, how hard you are to move doesn't figure into a Steelpushing contest.
  • Atium is amazing - great job on making it work like in the books! Only thing is I would have made it less than 6 rounds, if anything, that it burns for.
  • Buying extra vials of metal (say, if you know you'll need more than you usually carry for a job) - is that a Resources check?
  • The Rogue's Gallery is great for generic villains, but misses out most of the named ones. I can understand not statting the Lord Ruler (it'd just be you lose for most people) but Straff Venture? Cett Ashweather? (Though Zane is there)
  • If a player wants to be a Seer or Mistborn (we don't have one, but they have had some contact with friendly ones), surely they can't take a vial of Atium as a prop? Is there any way to replenish your supply without stealing it from nobles or the Lord Ruler?
  
  I realise this may seem very negative which isn't my intent at all, because this game has been great fun for all of us (and will hopefully continue to be, I'm typing this as we break for dinner), so thanks from everyone here for writing this.

The section on Destinies/Tragedies is really useful too, though it's hard to do if you don't have an hour or two to sit down and ponder. I've been running a week-long campaign now that Uni's out for the winter, and I've found that with the pace we're going at, I haven't really had a chance to work much of this in.

I've been telling my players they can spend Nudges to reduce damage by 1 each - though to a minimum of 1 total damage taken, once Equipment/Pewter/Mimicry powers/etc are taken into account.

[of 2-10 dice]

Per my reading of the rules, it already works that way in combat.

When forming your Action Dice pool, you declare how many charges you're tapping. This adds that many Action Dice to the pool.

When your turn comes around (probably first) you can form a pool of 2-10 dice by taking dice from your Action Dice pool. If you want to increase Outcome or Nudges on this roll, you have to declare at the tapping stage, which happens when you declare your action.

For Contests and Challenges, however, the fix above is still needed.

EDIT: I have noticed that they do seem to be superpowered anyway with this - a starting Feruchemist can stand to go toe-to-toe with a Steel Inquisitor and have a chance of escaping alive (even if they can't actually harm it) which even a starting Mistborn couldn't really hope to do, at least without Duralumin (which is a powerful Secret on its own).

"Slowswift" is also in the Last Names table twice.
