One, named only The Beast, is bigger than them all - almost the same size as the main building of Keystone!

Attack of the 50-Foot Whatever: Most bosses are bigger than you are.

Artificial Stupidity: Some enemies can get stuck on the terrain and just refuse to move, allowing you to attack them with no fear of reprisal.

Stop moving or start sneaking, and they'll either attack your last known location - or use echolocation.

Artificial Brilliance: The blind enemies (the Infested) can't see you, but they know you're there if you make enough noise.

Crossbows can be deadly after one or two hits. Even then, he won't make it unless you give him a Healing Potion.

Amputation Stops Spread: There is an injured monk that has been bitten by a spider and the venom has already spread too far to suck out so the monk's only chance of survival is for Harken to (rather stylishly) slice the afflicted arm off.

They can hide equipment, or even entire secret rooms.

Always Check Behind the Chair: Or bookcase, or barrel, or crate.

It likely has something to do with his Messiah Complex due to being a descendant of the 3 heroes known as the Judges who banished Adyr ages ago, leading to him wanting to essentially replace Adyr as humanity's godhead.

Why he takes the mutagen at the end of the game even though it looks like Harken has a decent chance of killing the Rhogar and Adyr is pretty inexplicable, though. The collectible lore entries and the 'Dark Experiments' sidequest explain that Artanas has been experimenting with ancient Rhogar-based mutagens in hopes of evolving humanity into a superior form, due to his belief that ordinary humans stand no chance against the Rhogar and will be destroyed.

All There in the Manual: Artanas' late game transformation into the monsterous final boss comes out of nowhere and is never really explained by anyone in-game.

She doesn't help Harken directly, but she does somehow manage to find her way to key locations, even if the only way through would be past a boss. She went to Keystone to find the secret behind an old family heirloom.

Action Prologue: The game starts with the cutscene seen in the trailer, with Harken battling a giant beast, and a meteor strike happens nearby.
