Chakra Origin still matters

Your Chakra Origin establishes which Nature or Heritage access you start with. The Path then builds on that existing access.

Extra techniques do not consume normal known slots

The techniques granted by Elemental Adept and Secondary Nature are additional selections, provided they satisfy your current maximum rank.

Not every technique is a Nature Technique

Universal, Heritage and Path Techniques do not automatically gain Elemental Adept, Elemental Shaping or Nature Mastery benefits. Those features specifically refer to Nature Techniques.

Higher ranks arrive from the base class

Choosing this Path does not accelerate maximum technique rank. Rank II, III, IV and V still arrive through the Shinobi class progression.

Origin and Path remain separate choices

A Shinobi's Chakra Origin describes what chakra or inherited power they possess; the Path describes how they train. An elemental Path can therefore be combined with different valid Origins according to the class rules.
