Advice on Blackened Half-Orc Oracle of Fire build

[TatterdWings]

SO I decided to try and be self sufficient and make a new character that can heal itself constantly so it can focus more on healing others without worrying about dying in the process. But I wanted to make it fun too so...

Half-Orc oracle

Mystery of Fire:
Burning magic @ lvl 3

Curse of Blackened = extra fire spells

Worshiper of Nethys

Alternate Traits:
Sacred Tattoo / Shaman's Apprentice / Fey Thoughts

Feats:
1 Fire God's Blessing / Endurance
3 Diehard
5 Fast healer

Convincing DM to let me make infernal healing permanent, otherwise persistent vigor permanent. Eventually purchasing ring of regen.

FGB + fire spells + FH4 + fast healer + Ring = ~ 10-12 HP per round in combat once i've managed to deal fire damage to something, and about 9hp a round outside of combat.

Looking for ways to change/improve/refine the build :)

I was going to use branded curse instead of blackened but GM said no because 3rd party and it was weird. Would have added CHA mod to Fort :( oh well.

Any and all advise appreciated :)

I really wouldn't go for diehard. Being a valid target when on -9 HP is asking to die.

Permanent fast healing via infernal healing or persistent vigor probably is broken. Don't be surprised if the GM says no to that too.

A pearly white spindle ioun stone (20K) is available earlier than a ring of regen, a cracked one (3.4K) earlier still. Sure, that applies only to out of combat healing, but it might still be handy.

If you want people to fail saves vs. your spells the dual-cursed oracle is good.

By the time you can afford a ring of regeneration 12 hit points per round in combat is trivial. You'll be taking 40 - 50 points if the opposition hits. If you are the kind of healer who shares the damage that your colleagues take, you may be looking at 100 hp per round.

Depending on the campaign -- how often your game master likes to push combats one atop the other -- out-of-combat healing is either straightforward (wands are a lot cheaper than rings of regeneration) or else counter to the campaign themes.

I agree with avr that Diehard is a meh feat, especially for a character with orc ferocity.

I should clarify that I've already mentioned the constant healing and how i plan to do it to the gm and he hasn't said no yet, also i wont have orc ferocity because as I have listed i'm taking some alternate attributes for flavor.

I also plan on taking the forge ring feat at level 7 and we will have a noble scion in the party that will help with the cost, also the campaign will be starting at 4th level so i'll have a little gold saved up already towards the 45k ill need in order to craft the ring. With the scion's help i'm expecting to have it done around 8th level. However the ring isn't even overly important to the build.

The whole point is that I want to be healing around 10 points every round just for flavor but i'm also gearing my character towards being an offensive caster throwing around fire spells at all times. I don't plan on doing too much healing, only as an option, because we have 2 bards in the group who are going to have companions who can heal, even though until later levels they will be a level behind the actual PCs.

I'm not making the character to be OP, just fun and flavorful. I know the healing isn't going to be very useful in later levels, and that's alright. Ive just had a bad run with a previous DM who liked killing off characters around level 3 so i want to guarantee that my character lives at least until level 10 or so. then if i need to build something new ill build something more OP :)
