New (Old) Monsters #1: The Ogre and the Giant

This time, two monsters! I will assume 5e rules but the challenge rating is somewhat arbitrary. My groups killed them like so. Wotc evaluation of their monsters and their rules for encounter-building are quite weird, so best make an evaluation yourself. If you think they are too difficult, raise the CR by a couple of points. 

Ogres are known for the never ending, all devouring hunger. They grow stronger the more they eat. 

The Ogre wants to eat and devour. They don't commonly form groups (since cannibalism is a reasonable worry) but sometimes even Kings come about, who devoured their own kind until no one is left.

Here a quick-and-dirty scenario to run with them: GROB and BROG teamed up to eat a local dragon and grab her treasures. Dividing the treasures was no issue - you can't eat gold - but dividing the carcass and to tasty bits turned out to be more complicated. The deal is to recover from combat and then 'argue' who gets which pieces of her. Some Goblins are hiding, trying to steal treasure and there even is an ancient priest in an ancient sanctum nearby. The heroes might have heard of the dragon hoard as they approach - the dragon has just been slain.  

Next is the Giant. Giants always just felt like big humanoids which made them boring. On the other hand, Old Giants are really really big and that makes them cool. 

Giants were strength incarnate. Once they had a blossoming culture and civilization but nowadays they are more a husk of their ancient renown. Not quite undead in essence, they are dead in spirit. Roaming around, seeking for the olden glory days. 

 

The quick-and-dirty scenario for the Old Giant is the following: The-Nameless-Giant rests on top of the highest peak, snow surrounding him. Ruins with treasures, beneath and next to him. The climb is quite dangerous and requires the heroes a couple of days of exhaustion. Goblins are nearby, as always, looking for treasures and ghosts roam the area seeking to kill living intruders.
