If you are planning to convert this over to d20M, it may be helpful to have the text of the anticipate action - all characters are capable of taking anticipate actions, but the cleric's class abilites give him some significant improvments. As it's a Wisdom-based defense bonus, the Clerics Wisdom requirment and bonus to wisdom score all feed inot this maechanic.
In d20M terms this is almost certainly a move equivalent action.
Anticipate (Initiative Action)
1 Half Action • Error Range +0
The character may attempt to second-guess the action of 1 opponent. With a successful Sense Motive (Wis) check (DC 10 + the target’s base attack bonus), the character gains a dodge bonus to his Defense against attacks made by the chosen opponent equal to the character’s Wisdom modifier (minimum +1). This check possesses the Vision tag. This effect lasts for 1 full round.
With a critical success, the chosen opponent’s threat range with each attack made against the character is reduced by the character’s Wisdom modifier (minimum 20). This effect lasts for 1 full round.
With a critical failure, the character is thrown off-balance, becoming flat-footed.
Special Note: A character may only benefit from 1 Anticipate action targeting each opponent at any time. If a character takes a second Anticipate action to boost his Defense against an opponent when a previous boost is still active, the new action’s outcome replaces that of the previous one — even if it’s worse.
Glad you like the class - I had a great time putting together a revised version for
Spycraft 2.0. The anticipate action let me really nail the feel for how Preston and co. operated in battle - they
out-predict their foes
