Tales of Arise - All Gigant (Elite Monsters) Locations

Elite Monsters are a stronger versions of monsters that you can defeat by doing some quests or simply defeating them as you explore. There are 20 of those, and you need to defeat them all to get the corresponding trophy. Nothing is missable here, so you don't have to worry if you missed some.

You will encounter your first Elite in Calaglia Realm, in Sandinus Ravine, very early in the game. No way you will be strong enough to tackle this one, so might want to return after you finish the story, or at some later point.

You can check your progress under Menu -> Field Guide -> Play Records -> Elite Monster Types.

Each Gigant unlocks an Astral Flower, which will give you +10 CP (per Giant!). You use CP for healing, and for map actions, such as removing the burning blocked paths, ice blocks and such.

Note that I'm using fixed map settings, and I will be giving locations based on that.
