In case you roll a ToS, I wrote a class guide about it too (sorry for that self-advertising lol), it’s more aimed towards level 80 but I included descriptions of almost every spell to explain what they do and what they are useful for (since that still matters for leveling as well):
The ToS is a really great class, since it provides great damage and healing you can always fill a DPS spot in case the group can’t find anyone else.
