Is Aid Grimel Sacred Urn combine trivial?

[Iilane]

After 3 tries at 227 pottery, I finally made an Unfired Sacred Urn for the pottery step in Aid Grimel's quest.

Before I toss the unfired urn into the klin, does anyone know if the klin trivial is 15 like all other klin combines? Or would you advice me to raise my pottery skills before firing the urn?

I didn't get a trivial message at 222, but I am 2/2 on the firing process.

I had no fails all the way through at 220, so you shouldn't have to raise skill.. just max your dex before you combine.
