There will be…at least 5 new spells in the next test, plus all of the runes in the game have been re-worked to their (hopefully) final forms. Fireball, Frostbolt, Mana Shield, Arcane Ray, Polymorph, Arcane Explosion, Affliction, Pushback, Ice Lance, and Decurse will be the ones that will definitely be in the next test. All of those are considered “basic” spells so the runes would be easily attainable in-game once the quests are all in, and for now the runes will be given out for those on the Wiki.
Fireball, Frostbolt, Mana Shield, Arcane Explosion, Affliction, Pushback, and Decurse all have more than one level to them. The Level 2 (and in some cases Level 3) versions of those spells will not be given out.
