I successfully completed my masterless Angel of Shotgunnery game to get Shottyman Diamond! Yay! :D (I'm not sure why my trait order doesn't show in the mortem; I guess mortem generation is still buggy) That Army of the Dead trait was super tempting every time I leveled up, but I resisted, and stayed true to my goal right to the end. :)
This run was helped immensely by the AV3 shotgun I found in Valhalla Command. It had a natural 4/7 range and Vampyric 2. It also had poison effect, which more often than not, was an annoyance, because if they die from the poison, I don't get the life-stealing effect of Vampyric or the AoSh Frenzy bonus. In any case, the addition of a Cold mod pack improved it even more, because not only was I able to fire quickly, thanks to the Reloader and Reload Dance traits, but all my enemies got slowed down, often multiples of them at a time. :)
Another thing that helped was a helmet that I acquired in Tyre Outpost that had "Nightvision" ability, which is described as "improves vision range in dark areas," which I would have assumed refers to the Lights Out event, but actually seems to increase your sight radius everywhere at all times! :o At first, I lamented the fact that I found it in a shotgun game, where I'm restricted to short range weapons, (it would be awesome in a game that allows rifles) but with the help of a bunch of accuracy mods and a shotgun amp, I was able to get my shotgun up to 7/8 range... able to hit enemies for max damage before they even see me. :) After that, the game was pretty much a cakewalk. Almost nothing could touch me, (or if they did, the Vampyre ability brought myself back up) :) and I barely used any med kits for the rest of the game.
I hesitated about getting Whizkid for a long time, but I'm glad I finally got it, because there are a lot of neat upgrades you can get. (Side note: I really like the new mod pack system; it keeps things interesting) :) It got me the auto-loader feature on my main shotgun and a couple of boosts to my critical chances.
The Summoner was completely trivial to defeat. In fact, I'm pretty sure he isn't supposed to be that easy. Bloodhound trait let me see where he was, and I just shot him from outside his visual radius. He summoned one enemy during his first phase, and for the second and third phases... nothing at all. He didn't summon or move, so I just kept shooting him until he was dead. This suggests that if you can get to the last level with a regular shotgun, you can always count on an easy time against the Summoner.
