Yeah, I recall the chart way back in the 3.5 DMG.  Clerics and oracles both eventually get cool stuff but at level 4 the concept just doesn't have enough meat.  I like that Heavens oracle gets color spray, but without a domain spell, oracles actually don't come out that far ahead of clerics in terms of spells/day plus I'd be losing out on channel positive energy.

What are your allowed sources?  Is it PF-only?

If you have access to Complete Mage, you could take the Fiery Burst reserve feat and play around with Heighten Spell to power it for some serviceable blasting.

If you're using point buy for your stats, I'd also recommend pushing your Wisdom to 20.  The benefits outweigh having lower stats in other areas.

PF only.  I'm not seeing the point in 20 Wis.  If this was 4E or something, sure, but when half my spells aren't even offensive, +1 to save DC and an extra first level spell just don't seem appealing enough.

Is there any good way to do this?  Burning Hands and Fireball don't seem like enough to really pull the idea together but there aren't many other options for cleric evocation.

Starting up with a new party, and I'm the 6th wheel.  They have a rogue/fighter and a paladin on the front line, a witch and a summoner taking care of your Int-primary arcane caster stuff, and an alchemist who alternates between mixing it up in melee combat and tossing bombs.  I've been told by several of them that they "need a blaster" which I know is kind of an overrated post, but I figured I could occasionally fill that roll with a cleric if I took the Fire domain.  It sounded better on my head than it comes out on paper.  Here's what I've got so far, but I don't really like it.

Maxis Drake
Human Cleric (Theologian) 4
Str 14
Dex 10
Con 13
Int 8
Wisdom 18
Charisma 12
Deity: The Elder God (homebrew)
Domain: Fire
Feats: Scribe Scroll, Combat Casting, Domain Focus

At level 4, this gives me a spell list that looks something like
1: Burning Hands (D), Burning Hands, Shield of Faith, Bless, Burning Disarm, Protection From Evil
2: Produce Flame (D), Sound Burst, Soothing Word, Hold Person

When we hit 5, which is supposed to be soon, I'd prepare two empowered fireballs and wrathful mantle.

The plan started to fall apart when I noticed that even if you prepare a domain spell in a regular slot (from the theologian ability) you can't spontaneously cure.  Of course, the paladin has really good in-combat healing, so my channels could probably keep the party going throughout the day.  Is this a terrible idea?  Should I drop Theologian and replace it with the Restoration domain? Should I just play a storm druid instead?  I like the flavor of my fire cleric, but the actual spell list is turning me off.  It's obvious that clerics at this level are supposed to be healbots or melee bruisers.
