Spell Cascade

I don't remember exactly, but I'm pretty sure they've confirmed it to not work with Flameblast (I think because it's channelled, but not 100% sure).

Curious to know of it works with Trap or Mine support gems.

They're both area targeted spells but already have similar supports (multi trap, minefield). I saw that Frost Bomb does triple and I suspect the other bomb spells as well.

Curious to see if Lightning Trap works with Volley (it works with L/GMP). A trio of those things kicking off simultaneously would shock the entire screen at once. Someone mentioned somewhere that Volley will not work with 'nova' type projectile skills (EK nova, sire of shards) so I'm not sure.
