Proficiency Question: Assuming Training Never Stacks?

[Neal Litherland]

Given the similarities to 5E, I'm making an assumption here that even if you receive training from multiple sources, it doesn't raise your proficiency a grade unless it specifically says so.

Example, half orcs have the option of being trained in Intimidation. Zon Kuthon grants his clerics the same skill. As such, I'm assuming that you can't take both options to become an Expert in Intimidation?

Correct, you're stuck at Trained.
