All Working Kingdom Under Fire: The Crusaders Cheats - Xbox

Delete Unwanted Skills
Many times, you may be tempted to delete skills from your officer or leader. If you want to delete a skill but cannot, simply switch the leader's troop job to any infantry job (all units require melee, so that is one skill you cannot delete) and delete the non-pertinent skills from that leader. Note that you will not be refunded the XP for deleted skills, so have a back-up save ready for times when your trigger finger slips.

Regneir: Extra damage
To have Regneir turn into flames and deal almost up to three times the damage as normal, during battle press [X], [Y], then hold [B]. To lay down a trail of flame and fire, press [Y] while you are in flames.

Mini-Game
To unlock the mini-game "Risky Raiders" beat the game with Regnier.

Officer Level Glitch
Higher level equipment usually yields better resistances, skills, and added effects. You can exploit the game's method of determining a officer's level by increasing the number of "pertinent" skills by changing the officer/leader's troop job into a job that has multiple skills. The sum of those skills will determine your leader's level. Once you assign that leader as an officer to your leader's unit, the officer retains his or her level, despite being in an infantry unit (i.e., the units under Gerald, Lucretia, Kendal, or Regnier).

Keep in mind that any high level equipment will be de-equipped if the leader's level suddenly drops because of a troop job change (hence the game message). This hint is more applicable for Kendal and Regnier, as their campaigns allow you to freely assign other troop leaders as personal officers.
