Chrono Trigger Walkthrough, Part Thirty-Six: Lost Sanctum (DS Only) Chrono Trigger owned by Square-Enix. Images used for educational purposes only. Take these items back to the bridge builder and he’ll give you a Haste Helm. Head to the Mountain in 600 AD. The Nu Guardian is waiting at the bottom, and he’ll tell you to find him at the. I once went to a Chrono Trigger party. I was the only. You won't need Marle either once you have Haste Helm / Nova Armor etc.
I think it depends mostly on the enemies and bosses you’re fighting. I personally prefer parties that include Crono and Frog with either Magus, Marle, or Lucca swapped in. I really like Ayla as a character, and she’s nice to use sometimes because her physical attacks are so strong, but I think I tend not to use her because she has no magic. I almost never use Robo, maybe it’s because I didn’t properly level him up but it always seemed like he got his ass kicked when I put him in my party. Constantly healing him was annoying.
