Giants
From Portals of Phereon Wiki
Killing and looting their corpses is how you obtain some Special Items.
Each new day, when you enter a portal, it rolls for a boss encounter, so if you're hunting for them enter each portal every day.
Killing a boss boosts the entire party's max morale by 2, you can even get more max morale from the kraken and lava fish if you don't harvest them.
