Enchanted weapons were able to break the bones that formed the Wights' bodies while darkness magic spells attacked their blood cores, snuffing the green flames that animated Kalla's minions as if they were just candles.
Yet instead of just disappearing, the flames reverted into small wisps that darted back into Kalla's body, who only needed a breath of Invigoration to give them new strength.
Before all the bone fragments of the dead Wights could touch the ground, the wisps were back, animating the lesser undead once again.
Conducting experiments about Lichhood on herself had taught Kalla a lot about blood cores and phylacteries. On top of that, she had learned how to imbue small amounts of her willpower inside the blood cores she created.
