Prism of Belief Warning - Many don't work

Just a heads up to anyone looking to make a large purchase of a Prism of Belief... Many different skills are just straight not working. Even relogging or zoning won't fix it. Some show a tooltip level increase but no corresponding benefit (ie damage) increase, some don't even show the level or benefit.

Biggest offender of this is Skeletal Snipers, all Prisms 1-3 do not give any benefit. It's why they're going for dirt cheap because they literally don't do anything.
