Finn

Finn is extremely similar to Shelly in terms of stats and skills, so he can be played near-identically. His passive ability, Reel In, allows him to become faster by 33% whenever a machine is finished. Since Finn will always receive a speed boost during Panic Mode, it's a good idea to preserve a little Stamina for it, especially if his Twisted version is present. One dose of Finn's speed boost does not negate the speed lost from the debuff applied by his Twisted counterpart, so you'll still need to be cautious. To his credit, when comparing him to Shelly, supposedly the inability never klepts your final increase; no net extraction gain could be valued over the raw survivability the additional Movement Speed grants Finn. In other words, the extra heart and 8% additional boost may make up for the reduced Skill Check value and lack of extraction ability, though it does depend on your personal opinion. Since Finn's Stamina is so low, choosing Well-Paced/Endurance will provide a significant increase to his strength and allow him to make use of his ability more often. Try to prioritize Stamina-based items. Astro is a good teammate for Finn due to his below-average Stamina.
