7th Ed. Plaque of Tepok question

Hello everyone,

As a new comer to the world of fantasy, I was wondering how the plaque of Tepok actually worked when choosing the extra spell... can you pick any spell within the Lore after choosing your two?

Thanks in advance for your help!

 

As I see it you just get 1 extra spell with the normal rules to get it.

 

All the plaque of tepok does is allow you to roll for one more spell then your lvl normally allows...lvl 1 rolls 2 dice, getting 2 spells, lvl 2 gets 3 spells, and such...
