TOPIC: Sacred Hand Grenade "To Hit"?

Just curious if the Sacred Hand Grenade would be like the Alchemist Fire, requiring an AC of 15 to hit, or if it would be like a Flask of Combustion requiring to hit the true AC?

Based on the description in the Quick Reference (as there is nothing for it in the 2012 Token Guide) -
Sacred Hand Grenade: alchemical thrown weapon which deals Sacred damage (Sacred damage is doubled vs. undead); counting to three is not strictly required prior to throwing [collect on use]

I think it would be like the Alchemist fire (it is an alchemical thrown weapon), but there is variance based on other items so I wanted to double check.

Assuming it works like the holy hand grenade of Antioch, one must count to three in proper sequence, merely throw it in the proper compass direction, and then even the most tenacious adversary is surely slain.

You need to hit the monster's actual AC.

Well, I know what I'm doing with all of my hand grenades... and it isn't throwing them at the monsters.

And what are you doing with them?

So do they only damage a single creature? I mean, they are hand grenades.
