I would never play this race, based on -4 Con alone. For the purpose of making a race physically frail, a -2 is sufficient. The double vulnerability is pretty brutal too. The limitation on fast healing is clever though. Rather than spell resistance, I think a bonus on saving throws against magic would suffice. Although giving them a spell once per day isn't the end of the world, I dont think 3rd level spells should be in the hand of 1st level characters.
1-A + or - 2 is a good brake when designing a race, going beyond that is risky as a playable race. It can both pigeonhole a race as a casualty waiting to happen or an overpowered Mary Sue. In this case, a Cha caster that is a glass cannon.
2-Two vulnerabilities that are far too common is a bad idea. As it is, they would find any but the most controlled place dangerous. A save mod would work better. That with the fear and reroll looks problematic. Doesn't fit with the luck mentioned.
3-regeneration in water would lead one to expect a more wet focused race.
4-Dispel magic is more powerful than a starting PC should be allowed. If it is that important to your ideal, perhaps allowing it as a racial spell, either gained automatically at the spell's level or even a level early. A number of races have powers that come with levels. That might be a solution.
I would like to see you 'final' run, the race seems too mono, yet scattered, but that can be fixed. As it is, they are Cha casters with a weak second going to Int based classes. Perhaps a Bard if they're less isolated.
My biggest issue is that it changes so many different things. Most the base races change or add about the same number of things. IE: 2 positive and 1 negative ability score modifiers with 1 feat like ability. All the penalties may make a by RAW balanced race but typically it leads to players optimizing around the weaknesses to abuse the extra strengths. Not arguing orc is an unfair race but it does make a very strong fighter because they can literally ignore all of the racial penalties that make them a balanced race.
I would drop the str penalty. Casters do not care about strength in most any case. Might add back on a penalty to CMD if you wanted to make them grapple vulnerable
-4 con is brutal. Lowering it and the cha bonus by 2 would make them feel less glass cannon. Also I might drop the cold vulnerability to help them keep them alive
Spell res and the dispel magic ability seem a bit redundant. Honestly I prefer a flat bonus to saving throws against spells to either of these mechanics. SR is often considered bad on PCs as it blocks beneficial spells from allies pretty well(typicality=CL) while fails to block most important enemy spells consistently(typically HD<CL).
The description tells about their origins but barely touches on what iniqi are like. What's their culture? What do they value? What personality quirks do they tend to have? How does someone roleplay as a n iniqi? These are the most important aspects of designing a race.
I pretty much dislike all of their class features except the healing one (very smart of you to cap the healing based on HD). They have whacky ability scores (most races should have +2 to a physical score, +2 to a mental score, and -2 to another score). I'm not crazy about just tossing reroll effects on a race as they're very powerful while giving very little flavor. It feels strange they have spell resistance when they come off as a magical race. And an immediate action dispel magic feels way too powerful to put on a race.
You could have just put it in this thread. Also, your new thread is on the wrong forum.
