I have finished the class
How does it looks:
- it's a class with 10 levels only (no epic)
- adds +1 divine caster level per level
- character gain 1 divine song on every odd level (max 5 songs total)
- song duration is based on spell duration (depends on divine caster level)
- DC of song is 10 + song level + WIS mod (for those few songs that have DC)
- I have removed requirement for Cleric (so Favoured Souls, Healers or other divine spellcasters can also get this class)
Any suggestions, should I change anything?
*I'm a bit disappointed by the class, it doesn't really advance any of bardic abilities.
