Realms Parchment to transfigure

[Kershell159]

Hi.
For Frostmourne.

Can upload the drop percent of the patch to transfigure or tell me the ways to get the transfiguration patch.

Sorry mi english is bad.

Your server has brought me a lot of nostalgia and many hours of play.
Thank you.

There is no public drop chance but players estimate 1-5%. They drop from lvl 80 raids, BGs and arenas.
