Persuasion Device

A side quest item from Dr. Beanies that permanently charms any non-boss enemy once per battle — the target joins your party as a familiar and fights alongside you for the rest of the run as long as they survive. The -2 Speed penalty is a real cost, but the ability to permanently recruit any enemy you can target is uniquely powerful for expanding your roster mid-run. Does not apply the standard Charmed status effect despite the name. Take it to the Boneyard to progress the associated side quest.

The permanent charm distinguishes this from abilities that apply temporary Charmed status. A recruited enemy persists between fights as a durable party member until killed, unlike turn-by-turn charm effects. Target high-value enemies — elites, powerful specials, or enemies whose attacks you've been struggling to deal with — to turn the most dangerous threats into allies.

The -2 Speed cost is acceptable on a cat that isn't speed-dependent. The one-per-battle restriction means you get one recruitment opportunity per fight, so prioritize encounters with the most desirable familiar targets. Completing the associated Dr. Beanies quest may unlock additional rewards or story content, making it worth carrying even if the charm mechanic alone wouldn't justify the slot.
