 ### Modified Items
 - The Mage's Book, earned from the Mage Training Arena, has been given the ability to swap between unlocked spellbooks.
-	- To unlock this ability, the spellbook needs to be added to the Mage's book. Take the Mage's book to the altar you pray to a spellbook, and use the book on the altar to add it.
+	- To unlock this ability, the spellbook needs to be added to the Mage's book. Use the Mage's Book on the Astral altar to add the Lunar spellbook, or the altar inside the Pyramid to add the Ancient spellbook.
     - Once unlocked, equip the book and operate it, then select the spellbook you want to switch to. This cannot be done in combat.
 - Crystal bow and crystal shield have been heavily modified. They no longer get weaker as they degrade, and the number of charges has increased from 2,500 to 12,000.
 	- The recharge cost has also changed. Rather than coins, you need 3,000 Rune Arrows to recharge the Bow, and 20 Rune Kite Shields to recharge the Shield. Purchasing a new bow or shield costs 20% more (3,600 and 24).
