[General Discussion] Overly Frustrating RPG Boss Battles - Sephiroth kicked my ass

Hmm, I've got some that haven't been mentioned yet it seems:

FFT:War of the Lions:

An Ill Wind.

The last multiplayer mission against:

10 Dreadnought Aragaths
All with Ragnaroks
All with Escutcheon IIs
Most with Shirahadori (Blade Grasp)
Some with Mana Shield and Soul Bind
Vampire and HP draining Shadowblade (or Duskblade, I forget)

Holy shit, this encounter was insane. I suffered through that with a buddy for a good hour or so, and the relief when they got rid of that bastard for the 3RD TIME was downright palpable. Oh, and the gear you win is fantastic. But still, that battle was about as rigged as you can get without using Arithmeticks (which are banned in multiplayer).

Okami:

Easy game overall, I didn't have trouble with the two optional Demon Gate challenges. However, the third was another story. If I had known the diffiiculty leap from the 2nd to the 3rd beforehand, I might not have attempted it.

You have to be absolutely flawless in your combos to maintain that free, damageless hit you can take. If not, it's a VERY quick trip to the screws, with cheap shots from all sides. The worst part was thinking it couldn't get any worse when 3 Butterly Raos, 3 Nagis and 3 Wakas (all superpowered) gangbang you.

There was a few times during that whole ordeal where I had to pause, take a breather and get a drink of water unless I did something I'd regret later.

Jam it back in, in the dark.
