I suffered a couple of deaths in the first hour, just due to QTE's that appeared without warning or explanation. After that I was pretty solid, until last night when I had my first 'real death'.
I chanced upon an Olog captain, sitting around a campfire, so I detonated the fire turning it into a spider frenzy. Covered in both flames and poison, every uruk in sight was obliterated quickly, but the Olog captain shrugged it off with about half his health left. I dumped all of my remaining arrows into his face, bringing his health very low, but then I got careless and he smacked me with a club bigger than my entire body, obliterating more than half my health pool in that single hit(I would later learn that the flames had enraged him). So I turned and ran, quickly drained a rat, just as I finished I had to dodge another club swing. This Olog moved fast for such a big guy. Seeing his health at only a sliver, I was emboldened to sacrifice some of my own health to hit him with a Finisher, which he countered. I should really start inspecting captains before I engage them. I attempted to vault up the nearest wall, but he just reached up and smacked me back down to the ground, depleting my remaining health. I nailed the death-save and tried to run, but more Uruk's had swarmed by now, and when I tried to vault over their heads the Olog captain smacked me out of the air. Unable to see the dodge-prompts properly from this position, I took another hit and was finally defeated.
After watching the nearly empty Uruk barracks replenish itself, I was reborn from the mists, and set out to claim my vengeance. Fortune favored me, as the Olog was having a party to celebrate his victory. I found the tallest tower, and from that vantage fired arrows coated in frenzy-poison directly into every vat of grog in sight. As the Uruk's and Olog became sick and turned on eachother, I grew impatient, and began releasing every spider, ghoul and caragor in the area. I really should learn to inspect captain weaknesses before engaging them. Terrified of the caragors, the Olog captain began channeling The Incredible Flash, and about 2 seconds later he was on the opposite side of the map. So I tracked him down again, and fortune gave me another chance, the arrogant fool was having another party! This time I let the poison do it's vile work while I waited patiently, and about 10 minutes later my foe succumbed to a mixture of poison and a hail of arrows from uruk archers who had turned on him. I claimed an epic sword from his corpse, and set about disposing of all the new captains who had appeared when I died.
