dont look at the build/weapon i was testing something, i use a 2.9% ls 900dps 100% crit dmg + socket wand for archon but i'm always getting one shotted against reflect dmg pack even worse with health link + RD
Assuming the gear you logged out in is your dps gear (aside from weapon), I have no idea how you can get one shot against anything on MP0-1, unless you're using the 1600% weapon damage Archon rune.
Two main questions: What armor spell, if any, do you use? And what rune do you use on Magic Weapon?
I run with Storm Armor - Scramble and MW - Blood Magic. The extra 1.5% life steal is very helpful, imo, so that should help against RD mobs if you're not using it already. You can also try Teleport rune on Archon, if you're not already. It gives a decent amount of survivability against elites because of the extra mobility.
Otherwise, to make RD mobs less annoying, increase your armor and/or physical resist. I'm up to almost 90% damage reduction in Archon form and I don't have any proglems with reflect mobs on MP1-2 with 210k dps.
Huh? You should be able to faceroll mp0-1 without your monitor plugged in while smoking, eating a cheeseburger, and being assaulted by a rabid gang of agitated wildebeests using that gear. RD packs will die and drop health globes before you die. Your gear is probably worth 2-3 times mine across all my characters and I'm crushing MP0. Can get a nice paragon XP farming build getting you 40mil+/hour with less than 2mil in gold.
