For better understanding your problem, let us know if you are REALLY using a V1.3 savegame?!
You say, you are a STARGAZER? Then it can´t be true that you only get Blessed Spirit in Empherian Temple. That´s REALLY bad. I have played 3 Races (Human, Elf and Thrall) and after placing the candle at Shrine of Celestial Light there were many spells available: Ward of Ice, Ward of Fire, Dispel Evil, Purify, Unpetrify and so on.
But, of course I never reached the Stargazer Class.... I would like to know, if the other spells like Breath of Air, Divine Grace, Regeneration and Divine Cure getting unlocked/available in higher classes or have to be found in chests.
Well, this is your thread, so let`s continue...
To get better Magic Spells you have to follow your (magic)guildquests!
Good traders for mages are: Aleister at Fargrove, rhe Witch at north of Devils March and the Runemage Grymlok at the Northlands.
For celestrial spells visit the temples at Fargove and Arindale.
But take care about your skills! If you cast Blessed Spirit (level 7) and your celestial magic skill is on level 6 the spell will fail! You cast, nothing happens.
The guildquests are written in the walkthrough.
I think there you will find all of your needs!
enjoy
