As far as 3-2 goes.... THE PAIN!!!
I'm getting better at it. I have a better idea of what I need and what I should be doing. Avatar described it best, it just requires airtight leveling and skill. It's quickly becoming one of my favorite dungeons in the game. It's simple yet very tough.
Do I take a 2-level higher kill or waste a good amount of blackspace searching for/executing a 3 level higher kill? Do I settle for a one level higher kill because there is nothing else in sight and I'm running low on space? When do I start in on the boss? Decisions like these are so common in this game and as you get better they become easier, but in this dungeon the decisions are frequently close and difficult to make. If you fuck up and make mistakes you probably aren't going to win. Of course you will get luckier layouts than others, but what it really boils down to is your strategy and how well you execute it. It's such a well-balanced difficult map.
I've bounced back and forth between prepping Namtar's Ward and the Dragon Shield. Namtar's ward is awesome for part 2 in both the leveling phase and the boss fight, but the Dragon Shield is ideal for part 3. In my successful run in part 3 I had Namtar's Ward. It's just so helpful for part 2 that I wasted minimal resources there. It's also really strong for the leveling phase in part 3 but becomes trash later on.
I feel like for me right now Namtar's ward is the better choice, at least until I get good enough at doing part 2 to where I can succeed consistently with the Dragon Shield. Maybe it's just the better choice overall? I dunno. It was still very useful for part 3 so for now I'm fine with it. My mind is open to other options as well.
Dragon soul is my most wanted item for sure. Small slot and it's just always awesome, but it really shines in part 2. Fireheart is real good as well and helps a lot in part 3.
Ideal glyphs for me for part 2 is imawal/endiswall. imawal without endiswall though and you can run into shitty situations like in the screen shot above
