Questions from a noob (about blood rager) and demon path

[Ulthar]

1. How long can you remain as a demon once you choose that mythic path (in the form). Is this something where I have to rest every 6 rounds etc.?

2. Do "Claws" count as fighting with two weapons?

3. Do unarmed strike bonuses stack with claws?

4. What are "iterative" attacks. There is a power called "Flawless attacks" which gives a -4 instead of a -5. What's that?

5. There are many "Aspects" of a dEmon. I tried the end game DLC to make a demon (lvl 20 bloodrager), but I could not determine how to actually "transform" into the demon. How many aspects can yuo have at once? It seems I have more than I can manifest at rank 10.

6. do wings do anything? (or just cosmetic) I can apparently manifest those as well.

7. How do I transform into a demon? I see videos of people as Balor, but I did not pick that aspect. I was hesitant because it said it filled all of my companions with rage and I thought that would disrupt spellcasting.

1. You'll get more with mythic levels. You can use the mythic power to have endless rage for the regular barbarian and bloodrager rage.

2. No, natural weapon is its own type of fighting. When you're using claws you're in natural weapon fighting mode, which is different from TWF or 2 handed fighting etc.

3. No, as a matter of fact dont ever try to mix both, unarmed strike bypass natural weapon fighting and you'll use your fists instead of claws, gimping your build. So no monk class nor improved unarmed fighting feat.

4. Iterative attacks are the consecutive attacks you do when doing a full attack. Each attack you do has a malus to attack of -5 for each attack. So the second attavk is -5, the third is -10 etc.

Flawless attacks reduce the penalty to -4, so you'll get -4, -8, -12 etc. It's like getting +1 bonus to attack for each attack you do in a turn.
For weapons and unarmed strikes, usually you get an additional attack after every +6 base attack bonus your character has on its last attack.
For natural weapons you need others means, like multi attack, or stack different types of natural weapons, like getting claw + bite + horn + gore + tail.

1. If you mean Demonic Rage, then it stays active during a whole encounter battle (as long as you have uses per day left). Note that Endless Rage does not affect Demonic Rage, only your Bloodrager's.
If you mean Demonic Aspects, then you can toggle them on during Demonic Rage or outside of combat (most of their bonuses shine only during Demonic Rage).
If mean the Demonic Form spell series, then it lasts for 1 minute per Demon path's caster level.

Only the latter actually transforms you into varieties of demons tho. The others aren't polymorphs.

I guess I am really confused then.

A youtuber Mortismal said to take a month rank for unarmed as a blood rager, Thanks.

as to transforming into a demon. I mean when I take the mythic path of demon, I do not know how to change into demon form and how many times before rests I can do it.

Demonic Forms are spells inside the Demon's mythic spellbook, starting from 2nd spell level. For instance, Demonic Form IV will transform you into a balor (amongst other choices). And as I said, they last for 1 minute per caster level. Mythic spellbooks use double your mythic rank as caster level.
