Teleport Contingency

This spell instantly transports you upon being reduced to 2 HPs or less to one location that you determine that you are intimately familiar with at the time the spell is cast. Upon arrival at your new location you are exhausted for 1d4 days.  Temporarily you also loose 2 points of Constitution until no longer exhausted. 

You can choose to suppress the effect of the spell for two rounds but the first round you will be dazed.  If you are healed to more than 2 hps the spell will go dormant until you are brought to the 2 hp threshold.  You will still be dazed for the first round that you suppressed the spell. 

The casting time is 1 minute but it is automatic in its use when you reach the 2 hp threshold.
