(1) Jon Yost and Staszek Bytnar, among others, have pointed out that the official ruling in Digest #110 regarding Cracks of Doom and Tookish Blood still leaves room for doubt. Here is a clarification.
--------------------------------------------------------------------------------------------
When it comes to corruption checks, there are no ties. If the character is successfully protected by Tookish Blood, then he is considered to pass his cc. See Annotation 23: "When a character fails a corruption check, the standard effects of this ( i.e., the character being discarded or eliminated and his items being discarded) are implemented immediately and are considered synonymous with the failed check. A card causing the corruption check may modify the standard effects of a failed check ( e.g. The Precious), but this timing would not be changed. Certain cards, e.g., Traitor, which do not cause a corruption check, but specify an action that results from the passive condition of a failed check, take effect as the first declared action in a chain of effects immediately following the chain of effects that contains the corruption check" (My emphasis).

(2) The question has arisen whether it is possible to use Under His Blow and similar cards to avoid being tapped by a detainment attack.
--------------------------------------------------------------------------------------------
You may of course us Under His Blow and similar cards in order not to receive -3 prowess for not tapping against a strike. However, if the sum of the die-roll and the character's prowess is less than the prowess of the creature, the character will still tap.
