first five levels of the Sorceress class outfitted her with the basics spell-wise. These next five levels, however, add plenty of tricks into the mix. There's still more direct damage to be had, especially with your first morale ability. However, a lot of what you're getting in levels six through ten are buffs and debuffs or Augmentations and Hexes, as Warhammer Online likes to call them.
Umbral Strikes is going to be your bread and butter buff for a while after you get it, as the spell gives everyone in your group a 25% chance to cause extra damage whenever they attack. One particularly interesting ability allows you to deal slightly more damage to a target of your choosing over a period of time, but less damage to everything else as a cost. This one seems like an obvious choice for epic monsters or maybe that particularly annoying tank in RvR. Your level ten spell is probably the second most important spell, next to your brand new buff. It's a classic AoE root that no spellcaster should be without, really.
