Oh, the fire tornado is just an idea for a somewhat powerful fire spell and completely something I am up for changing around.  It was just a silly idea with no real purpose.  I was just thinking of base elemental spells that could be used.

Ok so if I'm understanding you correctly, basically I can buff the gravity magic and just give AOE's long casting times.  I'm cool with that, but then I would need to think of something else for the tattoos.  They could provide a general base mild resistance to magic. (Or something else I would have to think of)  So, I can nominate allies to be unaffected and affect larger areas, but it takes longer to cast where I would be relatively defenseless while focusing on the spell.  If I got something wrong there let me know pls.  Thx.
