Trying to decide on getting Crucible

I will end up getting Crucible eventually, but there was a deciding factor I noticed when deciding whether I should buy it immediately or not: Devotion Points. Long story short, I was watching this video and noticed that it mentioned you can get Devotion points from Crucible. My question is does that mean you can get additional Devotion points from Crucible on top of the vanilla game ones? Or just get the vanilla game devotion points faster? Thanks for the help!

You just get them faster.

You can get devotion points on Crucible by spending tributes you get for completing waves. Your cap is still 50 points (or 55 for Ashes of Malmouth), so Crucible gives an alternative to getting your devotion points, but doesn’t change the maximum you can have spent on constellations.
