Shaundakul
Ever since he became the patron god of my 2e ranger.
Tyr, because he wasstoleninspired by the Norse pantheon. Gotta support my ancestors!
She's back to Bast, though, since Zandilar's back.
I picked Shaundakul as one of my favorites as well ... but it was because my (AD&D 2ed) Cleric of Mask pretended to be a Cleric of Shaundakul to join the party without them knowing he was evil.
(It was okay, the players knew. And he was "petty evil" that fit well with the "we have a good reputation because we do all these heroic things but we're really neutral out-for-glory-and-gold" party.)
