And let's you replace (not add), sorcerer spells with cleric spells.
It looks like when you would learn a sorcerer spell, you could instead learn a cleric spell. So it looks like you can add spells and also replace.
Conjure Celestial could be better than finger of death.Conjure Celestial, Aid, Guardians of Faith, Geas and others are great spells for the Divine Soul.
You just listed 8 spells, plus my list of 8 = 16.Then there are spells like Planar Ally, Temple of the Gods, Commune, Holy Weapon, and others.
Added, thx.
