Tips

 * Moult is very useful against regular Infested if placed during a jump - they'll keep attacking it without dealing any damage.

Trivia

 * After the poll on the founders forum she was to be named after Sarin, which is a colorless, odorless liquid,used as a chemical weapon owing to its extreme potency as a nerve agent. But when a first responder to a sarin attack suggested a name tweak, along with Sarin sounding too overall masculine, DE decided it was best to alter it to Saryn. (source)
