So at last! The harpoon! Commit yer Resourcefuls, yer Inspiring Presences, anything you can and ponder real hard on if you want em back in exchange for three resources and an action. Probably do. Getting more resourcefuls is like hard drugs. Do it. 100% won't regret it.
Item. Weapon. Melee.
Silas Marsh deck only.
: Fight. You get +1 for this attack. If you committed 1 or more skills to this skill test, this attack deals +1 damage. When this skill test ends, you may return Sea Change Harpoon to your hand to return all of your committed skill cards to your hand instead of discarding them.

In my Silas deck, this was usually a back up weapon. But then I realized the power of using this with Opportunist(2). That way, this becomes a pretty nice alternative to machete. The same technique can power your net. There aren’t a lot of great weapons in survivor if you can’t get chainsaw going for you consistently, this will do you well.
So, if I read this correctly this card does not interact with non-skill cards committed to the test. Makes you think how many skill cards you need to run in a Silas deck to reliably hit for 2 with this.
A decent weapon if you are committing skills to the Fight test, and, being Silas, why wouldn't you? The extra ability is nice, although, in my experience, Silas runs pretty lean on resources, so getting his committed cards back at the cost of 3 resources (and an action) might be a tough trick to pull off frequently, especially with his other signature asset doing more or less the same thing. If only we could have a Moneybags Silas....
With two pretty good signature assets and a hard but manageable signature weakness, it's up to personal preference whether you want to go with the "box," "book," or both signature sets. Those sailors, they are versatile.
