嗯，确实这样的话，如果是类法能力，PC做CELERITY的时候判效果已经出现了也不为过。
顺便请教一下姐姐，准备动作用DISPEL来COUNTER法术的时候，如果目标施法了，而PC在法术辨识后觉得不值得COUNTER的话，能选择不COUNTER嘛？
Later, the vrock returns with a friend in tow and the pair resume the attack on the party. After several rounds of violent maneuvers, the party corners both vrocks, and the two demons decide to tough it out and fight. One vrock, however, decides to use its mirror image spell-like ability to help it avoid a few hits from Sondranna and her allies. The vrock decides to use the ability defensively to avoid a hail of attacks of opportunity. Because the vrock is using the ability defensively, it must succeed at a Concentration check to successfully use the ability. The DC for the check is 15 + the spell level. Mirror image is a 2nd-level spell, so the DC is a mere 17. The vrock will succeed with this check automatically thanks to its Concentration score of +20 (there's no automatic success or failure on a check as there is with a saving throw or attack roll, see page 63 in the Player's Handbook), and so the vrock's use of mirror image won't provoke any attacks of opportunity this time.
However, let's suppose that Sondranna has seen this trick before and that she has readied an action to disrupt the vrock's magic use. The vrock's defensive power use won't interfere with the readied action (it only keeps the power use from provoking attacks of opportunity). Furthermore, let's assume Sondranna has received a bless weapon spell for her greataxe, making it a good weapon that bypasses the vrock's damage reduction. Sondranna hits and deals 18 points of damage to the vrock; the mirror image is not yet in effect because Sondranna's readied action interrupts the magic use, so there's no chance that Sondranna's blow will strike an image instead of the vrock. The vrock must make a Concentration check with a DC of 30 (10+2+18). 谁说不能打断了.
