Dude, you gotta go forward in time to the future and grab the sunstone. Take it back to Melchior who will then give you the Sword.

Yeah, what the other guy said. After getting the sun stone, put it back in the shrine, then go to 2300 AD and go to the sun shrine. You gotta fight a stupid stupid boss, but then you get the fully charged sun stone, which you use to make the rainbow sword.

>>3072445
When I go to the future the only person who can interact with the charged Sun Stone is Lucca.

>>3072460

That doesn't happen, you're lying. Delete thread.

>>3072474
No man, I went once and Frog was like "Imagine what Lucca could make with this!" And now it only wants me to make Wondershot with it, I'll make a shitty video and put it on YouTube if you need proof

>>3072486

Finish the sunstone quest.
Make the wondershot.
Then go see Melchior.

You are so fucking stupid it's unbelievable.

>>3072519
I had been under the impression you had to pick between the Wondershot and Rainbow

>>3072528
You don't. That would be completely fucking horrible game design.

>>3072537
Had to do it with Safe Helm and Swallow

>>3072663
Those aren't ultimate weapons.

Also every single end game quest revolves around one of the main characters plotwise so it only makes sense that they get their ultimate weapon.

The Rainbow shell is a bit of an anomaly because it's mostly to get armor that's "the best" but is usually not required, because of things like Vigil Hats/Haste Helms and Nova Armor.

>>3072537
In fairness that sort of thing happens in just about every Final Fantasy so one might expect it to happen in Chrono Trigger as well.

>>3072221
don't bother, game is overrated as shit

>>3072221
What they said

>>3072519
except him. He's being a pompous dick because he's a /vr/ guru which means something to him.

I've been here, you need the sunstone quest too. Keep going, this game is great and you haven't fucked up, just need a nudge.
