The large statue was launching sword after sword at the skeletons, keeping them at a distance for the most part.
More and more swords floated off a nearby weapon rack to replace the ones it lost, but they were quickly sent flying at Blue’s head as well as the other skeletons.
The skull was a smaller target so it was harder to hit. Blue only tilted its skull to the side to evade, but its necrotic helmet still took a graze.
Jay was too far away to analyse the large statue, but he already understood the danger of the upper floor: Get pinned down, and the truth guards will make you poisoned and bleed to death.
Thankfully the truth guards were already slain by now.
Other adventurers would have probably taken their time in dealing with them carefully and tactfully to not take poison or bleed damage, and would end up just giving time for the sword-levitating statue to attack, but this wasn’t true for the undead.
