I'm thinking about building a Heavens Oracle with Awesome Display, and I'm looking for things that synergize well with that, especially at higher levels where Color Spray will not be effective, even with the benefits of Awesome Display, high charisma, and feats. The usual options are obvious:
- Gnome (+2 Charisma and +1 to Illusion DCs)
- Maximum Charisma
- Spell Penetration and Greater Spell Penetration
- Spell Focus Illusion and Greater Spell Focus Illusion
Are there other character options that synergize well with this ability and allow it to be useful even at higher levels?
Note: My GM and I have negotiated a minimum 1/4 HD for purposes of Awesome Display. A creature would be reduced from to 1 HD, then 1/2, then 1/4 so if I have a +5 charisma a 3 HD creature would could as 1/4 HD for spells such as hypnotic pattern.
