Amethyst hammer is the second highest tier of hammers, tools used for breaking structures. Out of all the tools, they cost the most resources to craft. Hammers are useful because most spears and swords are not able to damage structures beyond wooden. Hammers can come in handy when raiding, due to them dealing significantly more damage to structures. This tool can be used to craft the Super Hammer when crafted with the Kraken Skin.
