| Asenfel's taking a wand of lesser vigor. He can even use it thanks to Deceive Item.
His primary tactics depend on the battlefield. If he has space, fly and use frightening chain to demoralize multiple giants (DC 18 will save or be shaken). If the fighting is restrained to the ground, he'll shatter nonmagical-looking weapons to reduce incoming damage. If we're facing one enemy that's clearly more powerful than the others, he can do an alpha strike: 9d6*150% damage empowered frightening spear from up to 250 feet away. That'll use up all the daily charges on his warlock's scepter and slightly reduce his chance to hit for the rest of the day, though. |
