Wow, they really went out of their way to make this card overpriced.
The basic purpose of this card is to boost will tests. In my opinion, if there were such a thing as a skill card which just boosts a will test and nothing else, it should give a + 3 bonus to be competitive with Guts. This card gives a + 2 bonus twice, so at least the bonus you get is better than the value of a single card in your hand. But once you factor in that you have to spend an action to play it, I think this card would be overpriced for the value of the will tests if it costs 0 resources, much less 3. The difference would have to be made up by the value of the combat ability. But I think the value of that is really very marginal. First of all, a combat test which does not give bonus damage is rather specialized, occasionally it will be useful but mostly it is not something you want to do. But the real hidden problem is the ordering problem, not only do you have to wait for just the right situation to come up where you need that kind of combat bonus, it also might come up before you have used the will bonuses, forcing you to sacrifice one or more of the will bonuses if you want to use the combat bonus. If you don't want to waste the will bonuses, you may have to wait for a really long time before you can use the fight bonus. This all comes together to make the card really quite marginal. If the card had a resource cost of 1, I would consider it to be not that amazing but at least interesting to try in appropriate decks. But a resource cost of 3 is just insane.
Now, the above analysis discounts the fact that this is an Item, and thus can be used as part of a combo with other cards that only work on Items. However, you had better have a pretty great combo for this to work. Merely having a deck that plays Scavenging is not enough of a combo, the degree to which this card is overpriced is just too great. Maybe a William Yorick deck could somehow put together a good enough combo for this, but I can't think of one.
