Simians and Longarm more specifically live in dense close knit communities and even when traveling find ways to maintain that bond through noises and pictograph messages. You have advantage on persuasion checks when talking to fellow Apefolk members. You can convey messages over great distances within dense forest environments using your Simian language. Messages conveyed this way are simple missives like Danger, Treasure, Warning, and Clear. Additionally when you send a written message you may write it in simian to disguise the message only for who is intended for.
When you are close to deaths door you enter a state of pure primal survival instincts. Once you go under 1/4 of your Max HP you enter a primal state.

Longarms have an odd natural touch with tools and crafting using this gift to build lush civilizations within their dense forests. You can choose one tool to gain proficiency with when you roll using tools with this proficiency you may double the bonus to your roll.
