New to Pathfinder 2e, need help with character concepts / builds

Due to circumstances that I am sure everyone is aware of, I am trying to learn PF2e. I have a couple of character concepts I was hoping to get some help with.

Kobold Sorcerer
He was a servant in a human nobles house, when some assassins tried to kill the nobles daughter. I used my breath weapon to try and protect her, but when it looked like I would fail against multiple attackers my sorcerer abilities manifested and I was able to protect her.
Her father rewarded me and released me from indentured service. I was told that I could continue in his service, but only after I had seen some of the world. I was given supplies and a small purse. I could return after one year if I wished. He wanted to give me the chance to become more than a servant.

Str: 10 +0, Dex: 14 +2, Con: 10 +0, Int: 14 +2, Wis: 12 +1, Cha: 18 +4
A – Ancestry
• Kobold (Spellscale)

• Ancestry Feat – Dragonblood Paragon (Kobold Breath)
• Class Feat – Crossblooded Evolution
• Class Feat – Greater Mental Evolution
• Ancestry Feat – Dracomancer
• Class Feat – Bloodline Focus
• Class Feat – Bloodline Wellspring

I am looking for advice on the build. Ways to polish the build to get more usfulness out of it. Etc. I don’t really know what to do with the skill feats yet and I haven’t even looked at general feats.

Elven Wizard or Summoner
For this one I really only have a concept, but I think it is a very interesting concept.
A man who went a little mad with grief when his daughter died. He found a way to “bring her back” at least part way. Through an Eidelon. He performed his ritual and an eidelon appeared that looked and acted for the most part like his daughter. He was shunned for this and so he and his daughter left home to make their way in the world.
He believes that the spirit of his daughter is part of his eidelon, and even calls her his daughter. Whether this is true or not is up to the GM. Either way he will have to come to terms with her death, and possibly his delusion that the eidelon is his daughter.

Notes
• Originally this was a Wizard character that took the summoner dedication feat at 1st level from the elf heritage or feat. Not sure which. But I am not sure how to make the eidelon strong enough to play a supportive role to him in combat.
• Should I just go straight summoner which would also allow me to be other races.

Your thoughts and suggestions on how to make this concept work would be very appreciated. Thank You.

In general that should all work fine.

One thing to be aware of for the second character is the difference between a Wizard with Summoner archetype and a Summoner with Wizard archetype.

The Wizard with Summoner archetype will have a lot more spellcasting power - but the Eidolon will be mostly only usable out of combat. You don't ever get Act Together or any other Tandem feats that increase your action usage during combat. So having the Eidolon do anything is at a pretty steep cost.

The Summoner with Wizard archetype will have a lot more focus on the Eidolon. It will be easily at least half of what you spend your time in combat using. However, you won't have nearly as much spellcasting power. A couple or four combat spell slots, and a few utility slots from the Wizard archetype.

Either can work just fine - just be aware of the differences and pick the one appropriate for the character and your goals.

For your kobold, don't forget skills and skill feats. You get a skill feat every even level, plus lip reading from your background. It's unusual that your heritage is blue, but your dragon disciple is gold. It's perfectly legal, but you might ask your dm about it.

Summoner is one of the more complex classes in pf2e, but I really like your concept. I might suggest a summoner with sorcerer archetype would be more powerful. You would be charisma casting for both.

For skills/skill feats on your kobold, look into Intimidation and the related feats such as Intimidating Glare, Terrifying Resistance, Battle Cry, and Scare to Death. Your 18 CHA will make Demoralizing easier and Frightened is one of the better conditions to apply. Plus, it makes sense for a psuedo-Dragon to be terrifying, though it would be interesting to see what he thinks of a servant doing that.

It is a heavy investment though when you also want to be keeping up your Arcana skill, probably.

Thank you all for the advice.

why 14 int

14 con would be very useful

combat-optimal isn't the same thing as fun-optimal.
