Marshmallow's Revised Revised Action Economy

[Heaven's Thunder Hammer]

Anyone have a copy of this?

[Dunnooo]

Necroing, but I'd also love a copy of this if anyone still has it.

Quite a necro, but if Marshmallow is still around: how do you handle spell combat? The text makes it sound like you allow a spell-and-attack for a single act action as many times as you have primary attacks, but that seems enormously powerful...
