Yes, you need to have them, you can either buy from the Shop tab, or you can buy them from Cruxs shop, i think its Fees and Cruxs shop.
I believe its 10 USD for toriprime and 7 USD for VIP.
At Crux/Fees shop its 200k Tc for Toriprime and 140k Tc for VIP
Toriprime lasts for 1 year and VIP is basically an extention too Toriprime, giveing you extra "abilities" VIP lasts for 6 months. Feel free too correct me if im wrong.
