Need some clarification on the Elemental School feature for the Elemental Ninja archetype.

Ever since I got the expanded version of Kobold Press' New Paths Compendium, I have been trying to make sense of what this feature gives to a Ninja with the Elemental Ninja archetype.

Elemental School: At 1st level, an elemental ninja
specializes in one of the following elements: air, earth,
fire, or water. This feature functions as the wizard’s arcane
school feature, except that the ninja’s selection is limited
to the elemental arcane schools as presented in the
Pathfinder Roleplaying Game Advanced Player’s Guide. She
uses her ninja level as her wizard level, and she uses her
Charisma modifier instead of her Intelligence modifier
for all abilities tied to her chosen elemental arcane school.
Wizard levels stack with her ninja levels if she selects
the same elemental arcane school as her wizardly arcane
school. This ability replaces poison use and the ninja tricks
normally gained at 4th, 8th, 12th, and 16th level.

Does this feature just give the Elemental Ninja access to the three school abilities in each of the Elemental Arcane schools (Advanced Player's Guide)? Ex. The Elemental Earth school's Earth Supremacy, Acid Fog and Earth Glide. Or does it give the three school abilities and/or the bonus spells from the Elemental Wizard spell list as well?

I raised the latter question because while I can see Elemental School feature replacing Poison Use. I am not so sure what replaces the ninja tricks at 4th, 8th, 12th, and 16th level. There are only 3 Wizard school abilities, so that would leave one ninja trick in need of being replaced. On the other hand, I could see those levels representing levels where the Elemental Ninja acquires a bonus spell from a given level of the Elemental Wizard spell list. 1st level= 1st level spell. 4th level= 2nd level spell. Etc.

So what is the archetype feature giving to the Ninja who has it? Thoughts?

Keep in mind that not all archetypes replace class features/abilities on a one to one basis. Sometimes one powerful abilty might replace multiple weaker abilities.

I’m fairly certain you get the elemental school abilities but not the spells. Keep in mind that those elemental school abilities are pretty powerful - most of them have more than one power packed within and/or scale up pretty nicely as you gain levels!

Okay. I had been wondering about such abilities replacing more than one class feature in a given class.

Would you be able to gain the bonus spells of the Elemental Arcane schools if you stacked the Elemental Ninja archetype with a spellcasting Ninja archetype like the Mystic Ninja archetype from Blood and Steel 2: The Ninja? *curious* The Elemental Ninja archetype replaces Poison Use and the Ninja tricks for levels 4th, 8th, 12th and 16th. The Mystic Ninja replaces Sneak Attack in order to gain the Mesmerist's spells and limited spellcasting (up to level 6).
