Link of pain Actor X to Actor Y, and then link of pain Actor Y to Actor X. Either one taking damage will now result in a stack overflow (and cancel the damage). Longer chains work as well. Any class can perform this with The Black Plate and the appropriate supplementary talents (either to use The Black Plate faster or extend the link of pain duration), but Demonologist is by far the best situated to do it since it has the actual Link of Pain talent; it's guaranteed to be able to do it at level 10.

For classes appearing in this list, I would say that AAD is clearly better with Adventurer, Possessor, Archmage, Paradox Mage, Radiant, Arcane Blade, Temporal Warden, Dark Priest, Revamped Anorithil, Arcanist, Zephyr, Spellsword, Demonologist, Brawler, Sun Paladin, Corruptor, Reaver, Necromancer, Anorithil, Stone Warden, Blood Mage, Alchemist, and Elementist. That's only 23 but there are a few more you can argue.
Static Field + AAD is basically only useful if you have Acera, and requiring a specific fixedart is pretty bad. Wyrmic lacks significant spell-attributed AoE damage which is the primary way of abusing AAD (use stairs to surround your target with AADs then use an AoE spell).
