Quick Intro to Some Rules

About Crystal Hall, from BoardGameGeek:

You are leading a guild of adventuring wizards through the Infinite Forest on a quest to find the magical Crystals of Power. If you can collect all four crystals, your guild will be the mightiest in the land. The Infinite Forest is a dark and mysterious place. Suddenly you emerge into a sun-drenched clearing and your eyes fall upon a fantastical building. At Last... Crystal Hall. You approach with caution and the doors slowly creak open. Before you is a glittering chamber and the very air seems to shimmer with magic. You sigh with relief ... until you see a host of other figures wearing brightly coloured hats and you realise: The battle for the Crystals has begun! Crystal Hall is the magical strategy game that encourages players to lead their wizard-shaped counters around the hall in a quest to uncover the four magical crystals that are hidden among the 36 face-down tiles. To win the game, you need to collect 4 Crystals of Power, each of a different color. To do so, you must position your wizards so that they are on a tile showing a Crystal of Power at the start of your turn. Each turn is comprised of 4 phases: Gather, Magic, Discovery and Draw. In the Magic Phase, you are given 4 units of Magic Power which you can use to move your wizards and attack others. Certain magic tiles can increase or reduce this total. During the game, wizards flip a multitude of magic tiles to discover curses, potions, spells, Crystals of Power and other surprises. During the Draw Phase, you get a spell card, which can help you with your quest. Do you have what it takes to be the most powerful wizard in the Crystal Hall? -description from designer
