A charge of magical energies ripping through the battlefield or a spell cast in haste in order to strengthen a caster's defenses can turn the tide of a skirmish faster and more decisively than any weapon or suit of armor. For many characters, the spells they know or prepare are far more important than any pieces of equipment they bring on excursions. Spellcasters of every stripe are constantly finding new and interesting ways to harness and use magical energies, be they divine or arcane.
Many of the spells presented in this section are tailor made to complement the abilities and talents of the new classes presented in the Advanced Class Guide, but still more also other classes. Even the gunslinger, ninja, and samurai will find some of the following spells appealing, though they will either have to multiclass into a spellcasting class or find a trusty spellcasting companion who can bolster them with these eldritch benefits.
