The Gem of Transmutation is a powerful artefact. Currently, it lets a person change their race and race specialization once per real life day. I believe with the introduction of multiclass this should instead allow the person to change their race once per RL day for each class.
For example, if I changed my class today to a INT grook for Monk. I have to either stay monk for that entire time or deal with INT Grook in my other two classes, which are BM and Bard. The race has a huge effect on all aspects of each class.
This is my idea: To change the Gem of Transmutation to allow one race change per day for each class I am. When I change classes it will also change my race and specialization to whatever it was saved when I changed my class. It also has a seperate cooldown per class. So if I changed to INT Grook on monk, switch classes and was a Horkval Bard, and two minutes later I change back to monk I am a INT Grook for 23 hours and 58 minutes for the monk class. So each class has their own separate cooldown.
