I played this card in George Barnaby and was left disappointed.
Only being able to do +1 damage once per turn is quite weak for a weapon. It makes dealing with 4 health enemies a pain and missing an attack against a 3+ health enemy means you won’t be able to kill it.
Furthermore, George wants to discard 1 card per phase. At level 0, his main way to do that during investigator phase is with Nautical Charts, so having Hand Hook or Anchor Chain to trigger his ability is quite useful in scenario 1. However, as you add cards such as Cornered, Bound for the Horizon, and Gift of Nodens to your deck, you really don’t want to be discarding a card to Hand Hook.
Overall, I have found Fire Axe to be a better card in George. It’s cheaper, has more consistent damage, and doesn’t “waste” a use of his ability.
