9) Highstorms, spheres, recharging stormlight, stormlight storage bar
10) Warcamps, troops, plateau runs.
more than enough for me to do for now. Speaking of which, I need modelers and texture-makers most of all, but coders, beta testers.... Really, anything you can do would be a HUGE help.
Some of the things on that list are unclear. Spren quests are our version of speaking the oaths- you do a spren quest, you get new powers. Anybody with an actual idea for what that could be is welcome to speak up.
Spren (aside from the companion ones) will be simple colored particle affects. Gloryspren come when you get a difficult achievement, kill a boss, or get a PvP kill. Painspren on damage, Angerspren when you hit something, Creationspren when you complete a complex crafting recipe, Exhaustionspren when you have low hunger, etc.
