28 to Zero
A perfect stealth roll, a betrayal by armor, and a round that ends careers.
Theren scouts ahead into the cave and rolls a 20 on stealth - nearly perfect, the kind of number that makes the table cheer. But scale mail doesn't care about your dice. The armor shifts, the sound carries, and every ogre in the cave turns to look. A goblin crits him for 8. An ogre crits him for 20. In one round, Theren goes from full health to face-down in the dirt. First death save: 9. Failed.
