You learn to use Warmage Tricks, special techniques that alter the way you fight, move, and cast your spells. You learn two tricks of your choice for which you meet the prerequisites. Warmage Tricks are described in the "Warmage Trick Options" section later on in the class's description.
Prerequisites
If a trick has a prerequisite, you must meet it to learn that trick. For example, if a trick requires you to be a level 5+ Warmage, you can select the trick once you reach Warmage level 5.
Replacing and Gaining Tricks
Whenever you gain a Warmage level, you can replace one of your tricks with another one for which you qualify. When you gain certain Warmage levels, you gain more tricks of your choice, as shown in the Tricks column of the Warmage Features table. You can't pick the same trick more than once unless its description says otherwise.
