Thankfully, the pain, while extremely intense for the Vespid guard, was at a level that could be ignored by Kain and Queen, feeling similar in strength to a stomach cramp but throughout his entire body.
Although the persistent pain did still serve as a distraction to him…
He could sense through the contract, that the guard's connection with Queen was fading. Clearly, whatever this pain was, it was killing the guard and no amount of healing skills or life-attribute energy was preventing the gradual approach to its doom, at most it was just fruitlessly extending its suffering. Therefore, Kain ordered for no more life attribute energy to be sent out. Once the guard dies, at least Kain would no longer have to deal with the pain.
Meanwhile, Bea released many threads and sent them towards his opponents. However, already aware that contact with the threads would result in the triggering of a mental attribute skill, all of the opponents dodged successfully.
