Temerity was getting tired of two things: the goblin games and the sharp pain in his chest every time he breathed in. And he hoped he could cure both of those items rather quickly. First, he gripped the arrow and gave it a sharp tug, pulling it from his chest. He then spoke a word and used his magic to heal himself (healing word, bonus action). With that completed, he pulled his crossbow from his side and placed it on the side of the cart, using it to steady his aim while he pointed toward the northeast. If that stupid goblin showed its face again, it was going to get a bolt to the chest. (readied action, when goblin 3 reveals itself, shoot with crossbow)
