I was brainstorming a blaster build and I realized blasters don't have a lot of options on their secondaries.
So I thought I'd pitch a few wild ideas to fill that. All ideas are selected based on there's a control and melee powerset in existance that you could possibly cherry pick stuff from if you ever decide to get saucy and make blaster secondaries.
Though mostly this is thow stuff at wall and see what sticks.
Kinetic Manipulation: Kinetic Melee attacks + gravity control's controls
Earth Manipulation: Earth Melee meets earth control
Luminous Manipulation: Might be a bit tricky but luminous assault melee + some illusion control... though I am second guessing this since illusion control is a bit of an oddball with no root but perhaps a version of illusory wounds that is melee..... maybe overthinking
Plant Manipulation: Spine melee (using the planty-spines as the default skin) + plant control
