No need to patronize a creepy voodoo shop for your DDO spellbook...

Darkgolem brings us the second in his series of spell descriptions for Dungeons & Dragons Online: Stormreach. He breaks down the effects and benefits of each Level 2 spell for the caster's repertoire. Dargolem also provides us with extra knowledge gained from his extensive research:

Much like Hypnotism, [Hypnotic Pattern] is very useful for causing your foes to hold still and do nothing while you defeat them one at a time. Of note is that the hypnotism effect does not have a duration, lasting until broken, even if you should leave and come back later, as long as the instance does not reset.
