So yes believe it or not I picked up TOME a couple weeks ago and started this Berserker as my first character. And today I beat the final battle, on the standard difficulty with adventure mode. I did use quite a few spoilers, and would like to thank the author of this berserker guide which helped a lot, as well as everyone on these forums for all the various tidbits of information posted here. If you look at my online profile you can see a few other low lvl characters I made, but they were made after the berserker, to check out other play styles, since this did get a little boring from time to time
I followed the above guide pretty closely in regards to the skill point choices. My most used skills were Rush, Stunning Blow, War Shout, Death Dance, and Death Blow, though I heavily relied on my passives and sustains. Crit and self healing were a huge part of my overall survivability, with the passives Bloodbath, Precise Strikes, Mortal Terror, and Vitality synergizing for a ton of damage and healing. I had over 60% crit by the time I had maxed out my dex and Precise Strikes, and once I found an amazing voratun axe with a whopping 34% crit chance, I was at about 100% crit. To that end I looked for items with crit multiplier and healing modifier and was constantly critting for a lot and while self healing. I also used the ring from the brawler arena which gave me life leech which also worked well with the high damage and healing mod. As far as other skills, I maxed both the +saves talents pretty early on but never really noticed a difference. Blinding Speed was very useful paired with the Thalore racial Wrath of the Woods to deal out a ton of burst damage. Though I maxed out Unstoppable in case of an emergency I never actually used it once, usually if I thought things were going bad I would try to teleport out of there and rest up with my infusions or my torque of psychoportation. One very useful thing I managed to do was totally eliminate the Rush cooldown to 0 by using a "Of the Dragon" armor, a War Master ring I got from one of the prides, and blowing a category point improving the tree Rush was in, this made mages in the final dungeons much easier to handle.
I was pretty conservative with my category points, I only unlocked Bloodthirst and used the rest on inscriptions as the other two trees available didn't seem that great. I feel this was a good choice as all 5 of my inscriptions (heal, regen, wild, controlled phasedoor, movement) never stopped being useful. The prodigies I chose were Irresistible Sun and Draconic Body and both were immensely useful. The Sun was a kickass AOE that only stopped completely demolishing almost everything around it by the time I got to the last dungeon. And Draconic Body surely saved my ass from death more than I would like to admit. Not sure exactly how I unlocked the Sun, the most I did was use fire damage weapons from time to time, but I wasn't aiming for it or anything.
My items were a huge part of my success, I found some really good ones throughout the game that I would swap around as necessary. Not just that amazing axe and life leech ring, but if you ever find those "Fists of the Desert Scorpion" gloves I'm wearing, KEEP IT! The stats are ok but the Mindhook ability it gives you is incredibly useful as it pulls enemies to you instead of having to Rush in. For other berserkers reading this, I also recommend keeping a full supply of rings/amulets with different resistances as well as several weapons that convert to different elements of damage. Swapping weapons according to an enemy's resistances was very important, and having the appropriate resistance equipment up is the difference between getting one shot and an easy beatdown. Though I did not go Antimagic, if I did it again I probably would as magic damage was easily my biggest weakness and swapping equipment around all the time got pretty annoying.
Well I don't know what else to say, I used up almost all my lives up until getting to the Far East but once I got there things were pretty smooth sailing. Only killing myself once, due to stupidly deciding to fight the room full of lvl 89 dragons in Vor Armory (I should go back and kick their ass). Things definitely got a lot smoother once I got all the crit/self healing talents going. The game was a whole lot of fun, very challenging and expansive, and I will surely try another character soon. Or try my hand at those bonus bosses I have heard of. I am very surprised myself that my first character managed to make it through the whole game, I have never had too much success with roguelikes so I think it was mostly beginner's luck and some great item drops. Thanks for reading.
