Ok here's my question.I am on Ascension Peak. i got the 1st and 3rd temple but i can't seem to find the way to the 2nd temple.Is the road somewhere near the cave? if anyone knows please help

I'm assuming you mean the one that has all the Trynnie statues? There are two different ways out of the main clearing where you had that big battle. From where you originally entered it, the one on the left will take you to the temple to use the last artifact while the one on the right will open up to take you to the final temple for the Ascension.

Otherwise check Xignal's map
