A quit deadly Mosquito Bite.

Prerequisites: BAB +1

Benefit: At the start of your turn, you may choose to focus on one single attack (this can be used with special attacks, e.g. Combat maneuver and Chopping Spells) this increases the action required to perform the attack to a full-round action, if it is not already, you receive a +2 bonus to attack rolls.

When doing so, you may not use attacks of opportunity, nor iterative attacks, nor bonus attacks through other abilities.

Special: Touch attack spells are still being cast during your turn, when increasing the casting time.
