With my hand on the device, I closed my eyes, allowing the shop to open. I immediately went to the section with class upgrades, and picked 'ArchInfernalist'.
I chose six skills, and upgraded them to the fourteenth level, focusing on the most useful in the realization of our plan. Those skills were: 'Control flame V', 'Create flame V', 'Mana V', 'Flame mastery II', 'Volcano eruption', 'Scorch III'.
This left me with 10 777 981 479 749 264 points.
For a moment I was wondering if I should invest it in additional mana, but then I realized it wouldn't change that much. After quite a moment of careful investigation of my skills, I decided on the best, in my opinion, way to spend those points.
