This is everything you need to know about how to recruit Orcha in Chrono Cross: The Radical Dreamers Edition.
How to Recruit Orcha
When you’re rescuing Riddel in Viper Manor (Another World), you’ll find Orcha. He’s trying to interrogate Riddel in his Hell’s Cook form. Serge and his party will have to fight Orcha to thwart his plans.
After being defeated, Orcha will show regret and ask to join Serge’s party.
He’s a good one to use in your party because he can deal a lot of damage, but you should watch out for magic attacks. His Magic Defense is very low, leaving him susceptible to those. Balance him with other characters who might do well with the magic attacks and try to utilize Defend.
