got 500.000 for start now.plan is start with something and slowly build it up but need tips/advice were to start
Not gonna lie, that isn't much to work with. I would probably start by getting a cheap stormshield with at least 24-25% block and at least 7% critcal chance (cc) (try to keep this piece under 200k for now), when you get better funds try to get one with at least 9% cc and better block. For now, I would try to get an axe of mace that has an open socket, strength (str), and does at least 1k dps (could find this for 100-200k). You also need more vitality (vit) and all resists (AR). Chest and legs will be the best place to find vit. You can actually find great deals on low level rings that have 30-50 str, 30-50 vit, 3.5%+ cc and 30%+ critical damage (cd) (less than 50k a piece). Keep an eye out for an Immortal King (IK) belt with a bonus to either frenzy or bash damage and IK boots - These should run you between 250-500k a piece. The IK belt is great because of the life steal, and two IK pieces gives a set bonus of +60 AR.
So with the 500k you have now get a stormshield with cc, and a higher damage weapon. Then go for the IK belt and boots (the boots have movement speed on them so you won't miss that from your current boots). Then probably a chest with at least 70 AR similar vit and higher str than your current. Then I would try to get a helm that has an open socket (put an amythest in it for +life%), str, vit, and AR. Then go bracers with 90+ str, 90+vit, 60+AR, and 4%+cc. You can also probably get a good deal on gloves now (a pair with str, high cc, high cd for less than 100k), but do not put this ahead of shield, weapon and IK items. Do not spend more than a million on any of the items in this paragraph.
After all this you will be rolling far enough along that you can save up and splurge. Target stats to finish Inferno and farm up to mp level 2 - 7,000 armor, 700 AR, 50k life, 50k damage (more of all these things is obviously better).
