Defend Charge (Ex)
At 4th level, a witchguard forms a bond with a spellcaster he has sworn to defend. Once per day, this bond allows the witchguard to spend a move action to grant an adjacent spellcaster a +2 dodge bonus to AC and a +2 circumstance bonus on concentration checks.
At 5th level and every 5 levels thereafter, these bonuses increase by 2. The bonuses last for a number of rounds equal to the witchguard’s Wisdom modifier (minimum 1).
At 4th level and every 3 levels thereafter, the witchguard can use this ability one additional time per day.
This ability replaces hunter’s bond.
The questions:
1) the text says that the witchguard forms a bond with a spellcaster he'd sworn to defend, but after that the text seems to refer to any spellcaster. How does it work?
2) move action to grant adjacent spellcaster bonuses for wis round/day. Does the spellcaster and the witchguard need to be adjacent all the time or just when he use this ability? If the first it seems pretty useless for a front liner.
