7. Ruin Sentinels (Dark Souls 2)

In true Dark Souls fashion, you enter a fog gate, fall several feet onto a platform, and get squashed by the Ruin Sentinel boss patiently waiting behind you. There is not just one boss either, but three of these guys are waiting to gang up on you with their ridiculously long weapons. The Sentinels are just normal enemies on steroids. This becomes apparent when you fight multiple sentinels later on in the game. However, those mobs are significantly easier to beat.

This could be considered as the Dark Souls 2 hardest boss if it wasn’t for the fact that this is Dark Souls, and in this franchise it always gets darkest right before it goes pitch black.
