Name Prerequisites Benefit
Ice Harmonics Bardic music ability, Perform (sing) 6 ranks.  
Icy Calling Con 13, Snowcasting.  
Ignore Material Components Eschew Materials, Spellcraft 25 ranks, ability to cast 9th-level arcane or divine spells. The character may cast spells without any material components. This feat does not affect the need for a focus or divine focus. 
Illithid Bloodline Ability to cast arcane spells without preparation, ability to summon a familiar.  
Impeding Attack Sneak attack +4d6.  
Implacable Base attack bonus +1.  
Imprint Stone Manifester level 1st. You can create a power stone of any power that you know. Encoding a power stone takes one day for each 1,000 gp in its base price. The base price of a power stone is the level of the stored power x its manifester level x 25 gp. To imprint a power stone, you must spend 1/25 of this base price in XP and use up raw materials costing one-half of this base price. Any power stone that stores a power with an XP cost also carries a commensurate cost. In addition to the costs derived from the base price, you must pay the XP when encoding the stone.

Inattentive   You take a -4 penalty on Listen checks and Spot checks. 
Incite Rage Cha 25, greater rage class feature. When the character enters a rage, he or she can incite a barbarian rage in any or all allies within 60 feet. (Any ally who doesn't wish to become enraged is unaffected.) The ally gains +4 to Strength, +4 to Constitution, and a +2 morale bonus on Will saves, but takes a -2 penalty to AC, for as long as the character remains raging. The rage of affected allies lasts a number of rounds equal to 3 + their Constitution modifier, regardless of whether they remain within 60 feet of the character. This is otherwise identical with normal barbarian rage (including the fatigue at its end).

Inspire Excellence Perform 30 ranks, bardic music class feature. The character can use song or poetics to grant a bonus to one ability score to his or her allies. To be affected, an ally must hear the bard sing for 1 full round. The effect lasts as long as the bard sings and for 5 rounds after the bard stops singing (or 5 rounds after the ally can no longer hear the bard). While singing, the bard can fight but cannot cast spells, activate magic items by spell completion (such as scrolls), or activate magic items by command word (such as wands). Each ally to be inspired gains a +4 competence bonus to the same ability score, which the character must choose before he or she begins inspiring. Inspire excellence is a supernatural, mind-affecting ability. Use of this feat counts as one of the character's bardic music uses for the day. 
Instant Reload Quick Draw, Rapid Reload, Weapon Focus (crossbow type to be selected). The character may fire the selected type of crossbow at his or her full normal attack rate. Reloading the crossbow does not provoke attacks of opportunity.

Saving throws and opposed rolls are not affected. An intensified spell uses up a spell slot seven levels higher than the spell's actual level. A character can't combine the effects of this feat with any other feat that affects the variable, numeric effects of a spell.
