20 Strong Tainted Grail Tutorial with a full playthrough

About 20 Strong: Tainted Grail, from BoardGameGeek:

In Tainted Grail, you will choose your path as four enemy types confront you, each one with a different level of difficulty and different rewards for taking them down. Shift between foes to build a well-rounded hero for a final fight against the boss. Combos in combat are critical as the dial severely limits the dice you can apply to enemies, but you can get around those restrictions by playing combat cards to unlock more options. The deck-building and combat card combinations change your strategy each time you engage an enemy! If you don't want to face a certain enemy or are scouting for a different one further down in its deck, cast it aside into the Menhir Stack at the end of an engagement. After eight turns, you will face off against an extremely difficult boss, who will bring one or more Menhir Stack minions along for the fight. If you defeat it, you've won the game! -description from the publisher
