Agility

From the Castle Crashers Wiki, the wiki for all things Castle Crashers

Agility is one of the four skills that a character can use in Castle Crashers. Agility affects how fast a player moves, as well as how far their arrows will fly and how much damage will do. At the beginning of the game, a bow is likely to do something to the tune of 1 or 2, and the player will move at a regular rate of speed. With each point put into Agility, a bit more damage will be dealt and the player will be able to move a bit faster. The Black Mace(+6) or Sai(+6) combined with the Meowburt(+3) Animal Orb increases Agility by 9, the greatest possible agility boost.

[edit] Notes

Agility is a hard skill to play due to the amount of movement from enemies and bosses. if you do play agility, you should either play through the game a few times to get the feel of it, or make sure you have another player for automatic potions and to keep the enemies near them.
