Spellcasting in Dungeons & Dragons is a complex and flexible system that allows wizards to cast a wide variety of spells. A wizard has a number of spell slots, which are used to cast spells.
Each spell has a Casting Time (CT), an Action Point cost, and a Spell Resistance.
A wizard’s spellcasting abilities are based on his Intelligence score, which determines the number of spell slots he has. He can also learn additional spells, which require additional slots.
A wizard can cast only spells that are on the wizard’s spell list. He must know the spell name and choose it from his spell list when he prepares to cast it.
A wizard’s spellcasting ability is enhanced by ability scores in other areas, such as Wisdom or Constitution. A wizard’s base attack bonus, for example, is increased by 1 for every 3 points of Intelligence bonus he possesses.
In addition, some wizard spells require him to make skill checks or roll dice to achieve their effects.
A wizard can use any weapon with which he is proficient and any shield with which he is proficient. A magic weapon adds its enhancement bonus to the damage rolls made with that weapon, while a magic shield adds its enhancement bonus to the AC rolls made with that shield.
