Spirit of the Warrior (3.5e Spell)

You become stronger, faster, more accurate and harder to hit. Your prowess in combat is truly something of which bards sing about. You can weather the toughest blows that your opponents throw at you.

Upon casting this spell, you gain proficiency with all simple and martial weapons, three temporary HP for every caster level you possess (which disappear once this spell ends), when using manufactured melee weapons your BAB is equal to your caster level (maximum of 20), and you use your spellcasting ability modifier in place of Strength to attack and damage for manufactured melee weapons.

Your base AC is set and equal to your ranks in Spellcraft (for sorcerers or wizards) or Perform (for bards) plus your spellcasting ability modifier + 10 regardless of whatever protective effects are affecting you or the armor you wear. Your touch AC is 10 less than your new normal AC, and your flat-footed AC is 5 less than your new normal AC. Modifiers to AC from feats (such as the dodge feat), size modifiers, and situational bonuses such as from cover change your new armor class, but bonuses from other spells, items, class abilities and the like do not change your AC.

During the duration of this spell, you also take a -10 penalty to caster level for any future spells you cast until this spell ends; this may stop you from casting spells of a certain level if your caster level is not high enough. For example, should a 15th level wizard cast this spell, his effective caster level would be 5, allowing him to cast up to third-level spells.

Material Component: A potion of bull’s strength, which you drink (and whose effects are subsumed by the spell effects).
