In the answer to this question Where can I find this Discipline that allows a Vampire to disbelieve in sunlight, stakes, etc. so strongly that it can ignore them?, there is a large block of source book text quoted. As per this Meta question What constitutes copyright infringement?, it sounds like it would be okay until someone from White Wolf complains?
Is there too much text quoted? Should we try to cut down the answer, perhaps removing the actual games rules and just leaving the 'flavor' of the power?
