How do I build a wide damaging field/aura? Not just skintight, but several hexes in size?

Emanation is basically "zero range" for an AE attack, plus immunity to its harmful effects for yourself, but doesn't change anything else including the need for an Attack maneuver.

The variant in Powers (Emanation + Area Effect + Always On) makes it a permanent field that you don't have to consciously use - it affects people automatically when they enter it, but only once (or possibly more, if they enter then leave then enter again, but in any case they aren't affected again while remaining in the area effect).

Aura + Area Effect (plus Melee Attack at -30%, if the base attack is normally ranged), per a PM exchange with Kromm*, gives you a Switchable field that continues to affect everyone in the area, once per turn, without any attention or maneuver needed on your part. You get the immunity that Emanation gives as part of the Aura enhancement.

So a 4-yard field would add Area Effect 2 (+100%) and the net modifier would be +110%. I don't see any conflicts: Aura covers the "free attack" effect, Always On addresses the "constant effect" angle, Melee Attack takes care of the "ground zero is at range zero" element, and Area Effect handles the "blankets an area" aspect. You can omit Always On -- for a net +150% -- if you want it to work like an ordinary Aura that you can switch on and off. The other aspects don't seem negotiable.
As of Pyramid #3/19, this is canon, with the following combination officially allowed:
