我记得说,如果是CXW给自己,除非把自己的血补满以后还有多的才可以"共享"给坐骑(或者反过来).
OK,找到了.
http://www.wizards.com/default.asp?x=dnd/rg/20050913aWhen the familiar and the master share a spell, they function as one being where the spell's effects are concerned. For example, if the master chooses to share a teleport spell with his familiar, the familiar doesn't count toward the spell's creature limit. Likewise, if the master shares a water breathing spell with his familiar, the familiar shares the master's portion of the spell's duration and does not count as another creature touched. A shared mirror image spell creates duplicates of both the master and the familiar, and a successful hit on either the master's or the familiar's image eliminates one duplicate master and one duplicate familiar. A shared protection from energy spell shields both the master and the familiar, but all energy damage that either the familiar or the master suffers is deducted from the total amount of energy the spell can absorb.
In spite of the foregoing, some aspects of the master and familiar always remain distinct. The master and familiar have two separate pools of hit points. If the master casts a cure wounds spell, the hit points bestowed must go either to the master or to the familiar. If points are left over after the chosen recipient reaches full hit points, the excess can go to the other pool. In a similar fashion, the master and familiar both have their own ability scores, and magic that enhances or improves an ability score must all go to either the master or the familiar.
Some spells have benefits that can be fully shared and other benefits that must be allocated to the familiar or to the master. For example, an aid spell grants temporary hit points and bestows a +1 morale bonus on attack rolls and saves against fear effects. If the master and the familiar share an aid spell, only one of them gets the temporary hit points, but both receive the morale bonus.
