A booster pack of ten cards (5 epic spells and 5 items), unlocked as a stretchgoal of the crowdfunding campaign for Boss Monster 2: The Next Level - but confirmed to also be sold separately at a later date. There are two versions of this pack. The original print includes "HSP006 - Final Form," while reprints replace this card with "HSP006 - Boss Fight!" (The card reuses the previous card's number.) 'Final Form' (with a different number) can be obtained elsewhere, but the reprint is the only way to get 'Boss Fight!'
