I have a level 100 TS Bauble from the CE and wondered whether you can use it before level 20? I.e if you've not yet chosen a specialisation will it recognise that and ask you which class you want or do you already need to have chosen, say, provisioner and worked through levels 1-19 before it works? It says it's no refundable so want to check... L)
Yup, Drona's got it! You can use the boost at any level, and you will be able to pick whatever specialization you prefer on using it.
