OP weapon in Thorium? Citation needed

This post is about the Blacksmith NPC. According to the wiki, once golem is defeated, the blacksmith sells a sword called the wyvern slayer. It says on the wiki that it does 135 base damage. However, someone on the Terraria forums has reported that it does 175 base damage, and with the Legendary modifier, 202 damage. I cannot confirm this, but if any of you can, comment below.
