Not true! Alpha monsters drop uniques. Monsters and undead are more or less similar for adventurers.
And as proof, here's my copied transcript:
After searching the area for 2 hours, following trails and noises, you finally encounter a large group of monsters.
You notice that they have a leader, an alpha monster, a really big and ugly one, whatever you want to call it.
The battle rages, you against the monsters. Your blows land true and you strike most of them down, while a few manage to flee.
The big one is the last to fall, but after an exhausting fight you manage to take him down, too.
In the lair of the big one, you find treasures worth a total of 2 gold, 3 silver.
You also find a unique item among the loot, the "Daemonic Jacket of the Kings".
And this can be found on my LP!
