All club members start earning this cryptobute once their membership is accepted. Devotion increases as long as you stay a member, and this delta rate can change as you interact with the club. You can never lose devotion, and it will be used as a tie breaker in any ranking.
Devotion Level - this cryptobute is public. It is a positive integer and is what you refer to as your "Devotion".
Devotion Points - only you can see this. It is also a positive integer, but changes every second. Each level takes more points than the last.
