Can some one please explain what is meant by "5 levels lower" with Kineticist Archetype Elemental Purist's Limited Buffer feature?
So far I get that you just get it and it benefits later at level 11. Isn't it?
Internal Buffer's benefits scale with your Kineticist level. It starts at 1 point maximum and goes to 2 at level 11, and 3 at level 16.
treats her kineticist level as 5 lower for the purpose of the ability.
line means you subtract 5 from your kineticist level to determine what benefits you get from the Internal Buffer ability. In particular when you get it at level 11 your limit is still 1 point since your level is 11-5=6. You'll get a second point at level 16, and the third point at level 21 (If your game allows for advancement beyond 20th)
