This thing is crazy. It's half of Ice Pick (3)'s reaction four times, except you don't have to discard it and it takes up no hand slots and it's free. I can't stress how important extra damage is on your own terms in this game. Getting extra clues for free is great, but doing the exact right amount of damage to an enemy keeps you from taking damage/horror yourself. Edge of the Earth has a few nasty enemies that care about doing any amount of damage at once, so this card is extremely useful to avoid shuffling in extra Tekeli-li. Oh, and the icons are insane -- if you have access to Well Prepared in this campaign, you take it.
