So i started a solo cipher recently, my first time playing that class, and just hit level 7 opening up the next tier of powers. I picked silent scream (stun and raw damage, nice) and Pain Block (only cipher heal i've encountered so far, and a defense buff, also nice) but upon trying to actually USE pain block, i find out i can't cast it on myself. This is not mentioned in the description, it only states that pain block may be cast on an "allied target", but pain link, another power i chose earlier, can also only be cast on an allied target, but it includes the casting cipher. Why the inconsistency? Is pain link the exception here, or the rule? Is there a way to avoid choosing powers that are useless for a solo run when i'm given so little info?
