How does AD really work?

Google states:

“Let’s say you have 100% Area Damage and you hit one enemy for 1,000,000 damage (including a critical hit). If Area Damage procs, it will have a 20% chance to deal 1,000,000 damage to all other enemies within 10 yards, but not the initial target. If you hit multiple enemies, each hit has a chance to proc Area Damage on the surrounding enemies.”

Does this mean that every enemy within the 10 yard radius takes 1,000,000 damage?

ChatGPT states:

"Each Area Damage proc deals 20% of the triggering hit’s damage.

Scales with your Area Damage stat, so if you have +100% AD, it will deal 40% (20% base × 2)."

Chat GPT is wrong in this case.

Call me crazy, but I’ve tried multiple times to change its mind (sharing different sources), but it won’t budge.

Simply anything with proc coeff higher than zero have 20% chance to trigger Area Damage 10 yards around the target by a ratio of initial damage depending on your stack of AD% stat. There is an article on it at maxroll, I wouldn’t trust Artificial Intelligence models for something I can test in-game or gather information from different sources.

You need a skill that has Proc coefficient higher than 0 (those are kinda “hidden” for D3, if you played D4, that would be similar to lucky hit there).

Basically, if you hit a mob for 1M damage and this one is surrounded by 5 mobs, and you trigger AD you will hit the other 5 mobs for at least 500K damage (based that you have 50% AD from paragon).
