Devotion

[An Angry Fatman]

Can you tap mana to add to your devotion count? Like activation of {Nykthos, Shrine to Nyx} with devotion of 5. Can you tap mana to add to the devotion? I don't think so because they aren't permanents, but he makes good points lol.

No you can not

700.5. A player's devotion to [color] is equal to the number of mana symbols of that color among the mana costs of permanents that player controls. A player's devotion to [color 1] and [color 2] is equal to the number of mana symbols among the mana costs of permanents that player controls that are [color 1], [color 2], or both colors.

Devotion counts only mana symbols in your permanents' mana costs — the cost in the upper right corner of the card.
Mana symbols in text boxes of permanents you control, such as activation costs or the big mana symbols on basic lands, do not count toward your devotion to any color.
Only colored mana symbols count; it doesn't matter how much a permanent costs to cast, just how much colored mana.

I.e.  {Force of Nature} green devotion is 4
{Obzedat, Ghost Council} white devotion is 2 and black devotion 2
