Defense
From the Castle Crashers Wiki, the wiki for all things Castle Crashers
Defense is one of the four skills that a character can use in Castle Crashers. Defense affects how much health a player has and how resistant that player is to attack. With each point put into defense, the player will become more resistant to damage and gain more health points, allowing them to take more damage without dying. Specifically, a character's health is determined by the formula:
Health= 69 + (3 \times Level) + (28 \times Defense)
The highest defense bonus is currently an Evil Sword and the Snailburt animal orb yielding an +12 to defense for the cost of 5 agility.
Defense is best played as a secondary skill, if you are playing in a single player campaign. However, in a party, having lots of defense acts as a "tank" or a damage taker. Tanks are very useful in a group of three or four.
