Something quick and simple tonight and more advanced stuff later in the week. Three creatures to help offer a chalenge in the later heroic teir.
First, the Solo Hill Giant.
There are no immediate reactions, or bloodied abilites to keep track of. The Hill Giant wants to be in Melee and use Sweeping Club as often as possible, traping the PCs in a corner if one is easily available.
Pair with Striker and/or Artillery if facing five or more foes.
It's Lightning Breath offers just enough control to help it keep PCs where it wants them and away from anything or one it might be protecting.
The Guardian of Malkind uses it's Shield Slam to move targets around, and War Hammer Sweep to keep them where they are. If Malkind is not available in your campaign Moradin or another warrior god works fine.
The Guardian's work well as a duo, with Malkind's being immune to Lightning, as well as seoarate in a mixed group.
Set them up as temple Guardians guarding an importnat artifact or statues come to life by powerful magic. If springing a surprise or waiting for something to happen, like someone grabbing the treasure in the middle of the room, before attacking, the Guardian's use Bluff to appear inanimate.
