familiar with ancient guardian this will absorb 1 attack every 6 sec for you just in case you drop below 35 percent life.
diamond skin to with crystal shell - use this to heal it will give you enough time for your regen counter to tick in
magic weapon with blood magic the blood magic so whenever you attack you get life back
energy armor with force armor. this is essential so that you only take 35 percent of your life in damage at any time.
archon because why the hell not.
glass cannon "more damage means more life with a weapon that returns a percent of damage done in life"
galvanizing ward " increases your energy armor time and will heal every second"
unstoppable anomaly for once again just in case you almost die
now for gear focus on intelligence only with very little to no vitallity so that when you hit you heal more life using items that give life back based on a percent of the damage you do and get health regen too.
and as for a follower use the templar with loyalty to also add to the amount of life you recieve back
now lets say you have
5000 health (thats with very little to no vit on all your items) each hit will do about 1750 damage to you thats 35percent
your templar with loyalty and galvanizing ward will give you about 500 back a sec
now all you need is a high dps weapon that has life steal and armor with health regen or +life on hit totaling the other 1250 or more and you will be able to solo inferno
remember if you still get low use a health potion and repeat
you will kill everything before they can hurt you now you may die but im sure you killed some of what killed you now respawn and finish off the rest.
have fun finishing inferno everyone.
