Bloodrager's archetypes

[Trisagon]

Hi Everyone, I am building an Abyssal Bloodrager and have just started looking into archetypes. RAW, can I combine Crossblooded with Untouchable and Primalist?

[Ryze Kuja]

You can combine any mix of archetypes but only as long as the abilities and class features that are modified don't overlap each other.

Technically, Crossblooded Rager modifies the entire bloodline, spells, bonus feats, etc., and Untouchable modifies spells while Primalist modifies the bloodline.

So, short answer: no.
