The next stage of Guild Wars 2's multi-part Icebrood Saga finale is here, and with it comes a steeper challenge to tackle. Following the MMORPG's first finale chapter's introduction of Dragon Response missions, the latest - 'Power' - brings a bunch more, and you can expect their bosses to throw a meaner punch at you this time around.

"In Chapter 2’s missions, you’ll see some new foes and, in particular, upgraded bosses," Episode 5 team lead Joe Kimmes tells us. "We were a little more cautious in the first chapter as we eased into the Response Missions, and now you’ll begin seeing some larger-scale attacks from the bosses, in particular if you turn on Challenge Mode." As for what this challenge mode modifier does, the dev explains that it ramps up the big bad beasties' skills in various ways.

"In addition to stat increases, the Chapter 2 bosses upgrade their skills in challenge mode, from tougher summons and stagger mechanics to varied and more dangerous AoE patterns." Gulp.
