Stamina and the Warlock
From Basin Wiki
Equipment wise, using the Afflction set of talents, a warlock's best stat is Stamina, followed by Intelligence, and after that nothing else really matters. Spirit is not neccessary at all for a warlock due to how the mana recovery spells and talents work.
The overall point is using your hits in combination with the pets mana to supplement your mana pool. The increased damage and hits return of drain life combined with death coil and life siphon then helps to replenish life, while simultaneously increasing overall damage done to the enemy. Therefore the number one stat for mana recovery is not spirit, but stamina. More hits will mean more hits available to convert to mana - it ALSO means being more durable which will mean the ability to last longer to cast more drain lifes. A mage cant kill you as quickly if you have 4000 hits + at lvl 60 (at 53 unbuffed I had 3200 hits\3300 mana), which will give the warlock enough time to dish out damage and replenish life, and thirdly giving you enough time to last for a possible nightfall kicking in.
All a warlock's equipment then should be focused around stamina. The talent Demonic Embrace increases stamina on a % basis, so the higher one's base Sta the more effect the talent will have - so its a great combination. Each Sta point will give 10 hits, while each Int point will give 15 mana. Intelligence is the next useful stat, with having a larger mana pool will mean less life reducing lifetaps are needed in the first place. Still though, due to the mana recovery, a warlock can have the benefit of 3 regens occuring at once (hits\mana and pets mana) so it's always useful to have a lot of hits for lifetaps. Say life is at 95% and mana is at 40% - the best method is to reduce downtime by life tapping and getting both to 60% rather than staying near 100% life and waiting on mana regeneration. Toss in few dark pacts and he goes to 60\80% and 70% on the pets mana bar and are then ready for the next fight. Intelligence, while being important is not worth sacrificing Stamina for, the perfect class of items though are random cloth with "of the Eagle" bonus, which is +Sta and +Int.
