Kinda noobish questions, sorry! A lot of prepositions are also used here Sorry!
I've been playing D2R largely blind. I have a Paladin was specifically created to work with my girlfriend's lightning sorceress. They were in two of hell.
Solo characters playing and have an assassin who has just been thrown into hell and a barb in the 5th act of the nightmare (having some issues in the battle between the ancients.
I was having lots of issues when I was playing melee characters in hell and nightmares. I assumed it was simply my play, so I began to search for assistance. The horadric cube is much more than just combining three of an item to upgrade something to upgrade, for example, upgrading equipment.
I chose to upgrade my barbarian Soulflay, Shadowfang and... It's completely different and that's how I ended up in nightmare 5. A little later I received blood letter, which I used to replace the upgraded shadowfang (really did not know which to discard and so I turned one coin, then placed the other one in the stash.)
My issue is having to lose a second weapon, with an 8% mana steal. I manage my mana fine however I'd prefer it to be more efficient. I'm in the middle of ridiculous amounts of money. I can gamble on 7mil, and still be fine. I'm aware of how much attack and resist is going to be is going to be a problem come to the end of the road, but I really need a mana to steal.
I'm aware that runewords are an important thing however it can be overwhelming. I've saved every rune we have, and haven't even ever used one as of yet...
For mana-related issues, the insight runeword that comes with your mercenary makes a good option. Insight provides the level 14-17 mana regen aura, and will resolve most of those. It is recommended to do some research before creating one, as there's nothing to lose.
More than mucking up the more than mucking up a side note of D2R Items, in case you didn't know that auras that originate from the gear stack can be paired with whatever you're using as a Paladin therefore you and your girlfriend might both be receiving that mana regen as well as whatever you use normally.
