Your study of cantrips has led to more efficient and potent cantrip usage.
Prerequisites: Must be able to cast at least one cantrip by way of a feat, spell, spell-like ability, supernatural ability, extraordinary ability, or other means.
Benefits: The benefits of this feat are dependent on your ranks in Spellcraft or Arcana, as follows:
0: Learn a number of cantrips known at first character level, and each subsequent level thereafter, equal to your Intelligence modifier
4: You may count a cantrip as being 1/4 spell level, if it is beneficial to do so.
9: When combining cantrips by some ability or using the Widen Spell metamagic feat, you can widen the cantrip(s) cast by one step for the cost of just one cantrip per step.
14: When combining cantrips by some ability or using the Extend Spell feat, you can extend the duration of the cantrip(s) cast by one step for the cost of four cantrips.
19: Cantrip Metamagic Master: when calculating the cost of metamagic applying to the casting of cantrips, you may calculate the cost using cantrips at the same rate as you would normally use spell slot level increases.
