Prismatic:
You will be using one (and only one) of these to fulfill your meta requirement. Use it in a blue slot, preferably one with a good socket bonus (like str).http://elitistjerks.com/f76/t68951-r...updated_3_3_a/Yellow slots:
If you have ONE socket in a piece that is yellow with a STR bonus of 4 or higher, you can safely use these - a piece with 2+ yellow sockets is better off gemmed with pure STR.
