Advice on Kineticist: Single Gate Air or Dual Gate Air/Water?

Hey everyone,

As the title states, I'm currently creating a new character for our homebrew campaign. They will be a 7th level Nagaji Kineticist. I initially planned out their build with just the Air element in mind, as I do want the character to be sneaky and the invisibility impulse at 6th level did sound quite interesting for that in particular, however I am trying to see if I could possibly fit in Water as well for thematic/backstory reasons and to have some versatility in AoE impulse options perhaps, but I find it hard without sacrificing that which I had in mind in my original, single gate build.

Here's what I originally had in mind:

Level 1:

  • Single Gate: Air
  • Whisper on the Wind
  • Aerial Boomerang
  • Four Winds

Level 2:

  • Kinetic Activation

Level 4:

  • Safe Elements (For Desert Wind down the line)

Level 5:

  • Expand the portal: Aura Junction
  • Lightning Dash

Level 6:

  • Cleas as Air

Level 8:

  • Elemental Overlap: Desert Wind

Level 9:

  • Expand the Portal: Resistance
  • Cyclonic Ascent

Level 10:

  • Aura Shaping

This will be combined with FA to grab either the Rogue dedication (Mobility feat & general skill feat improvements) or Monk dedication (Higher will save eventually, status bonus to move speed to not pick up the Air Aura possibly?).

Now, I'd love to know:

  • Anything I missed on the single element build?
  • How would you go about combining Air & Water while maintaining the initial character idea? I'd like to incorporate water at current level (7)
  • How would Air/Water hold up against the damage output of mono Air?

Thank you for reading and I would love to hear your thoughts.
