Is there ANY actual reason to choose this Creed over anything else?

It comes WAY too late, literally every spell it offers is attainable either as a pickup or in another Creed, the healing item sucks, and it's placed at the end of one of the worst platforming sections I've ever seen.

I would think Devara or the Order of the Betrayer are the superior choices for a mage, myself. Devara mostly because of the Creed items (2 of them restore Focus and Stamina, and one is bar none the best healing item in the whole game) and the Order just utterly stomps all opposition.

Ngl, clarity is probably the only reason to choose this, over the Order of Betrayer

It took me four and a half hours to get to him. The print of that moment is my image on the desktop.

if ice magic wasnt scrapped, this Creed could be Keepers of Ice, Fire and Sky instead... as how it's reflected in
the ending line

This creed, while really cool, comes way too late in the game. Especially when you compare it to House of Splendor and The Stone Roots.

Both of those respective creeds come early enough that you can benefit under them for most of the game. Meanwhile this one is so late you get to have a grand total of 3 zones with them before the game ends, and you will probably have all the rings and most of the spells beforehand.

Not to mention even the "hidden evil lategame" faction, Order of the Betrayer, can be obtained EARLIER than this one, has an entire exclusive set of spells and armor, and has arguably better buffs/debuffs.

I hope in Salt and Sacrifice the Creed equivalents are spaced out a lot better and more balanced. The system is really cool and an interesting take on Fromsoft's covenants, and should be improved rather than tossed aside.

This says, "joining The Three does change the ending". And also, prices and devotion reqs for spells/incantations aren't listed for some.

The trick to the jumping is casting mid air slows your falling makes it easyer
