Iruxi Unarmed Expertise does nothing.

The CRB errata completely nullified the 13th level Lizardfold Ancestry Feat Iruxi Unarmed Expertise.

Your unarmed attacks blend tradition and training. Whenever you gain a class feature that grants you expert or greater proficiency in certain weapons, you also gain that proficiency in the claw and unarmed attacks you gained from lizardfolk ancestry feats.

The errata gives this exact ability to every PC.

All Classes for Unarmed Attack Proficiency and Benefits
For any class feature that improves the proficiency rank or grants the critical specialization effect access for simple weapons or a specific set of weapons, that ability also grants that benefit for unarmed attacks.

Please give Lizardfolk a 13th level Ancestry Feat that actually does something!

Technically it does something for one class, wizards as they don't get simple weapon proficiency.

But yes, it is relatively garbage and should be fixed.

So that's basically everyone and so everyone eventually gets their best possible unarmed strike proficiency?

[Squiggit]

Correct.

For my House Ruled fix, I said that the feat increases the die size of all Iruxi ancestry-based unarmed attacks by 1 die size. So a 1d6 Tail attack becomes 1d8, a 1d8 bite becomes 1d10, etc.
