Assuming your friends are offline and you are so bored of speed leveling gems that you only have 1 or 2 L25 Gem of Ease gems. Whats the "best" build to p-level yourself to 70?
What difficulty can you expect to play going in to the high 60s? All 2H weapons with a VIT roll will breeze through early game in T6 but in my experience it's quite a bit more dangerous as you level up.
Of course crafting yellows along the way and using all slots in the cube is viable.
Suggestions/ideas for all classes welcome, although I personally is most interested in WD.
*Either* Wormwood+RoE *or* SMF+TMF+MoJ+TnT. Both doesn't make sense, since pets don't benefit from RoE.
I personally would go for the WW+RoE route as it's only two items and it deals absolutely insane damage, you'll be able to breeze through T6 with ease until the late 50s or even beyond. You can still have pets as a meatshield, btu the main damage will come from your LS+Haunt. You could even put both in cube and then put the two level 25 Gems of Ease on non-class specific items in case you want to switch later (i.e., something like Furnace+an amulet with 10/100 and re-rollable elemental damage/main stat). Use the cube recipe for the weapon as well with Gem of Ease to be able to use an emerald, craft some random rares with CHD/CHC in the respective slots, and use Flawless Royal Topazes in your armor slots. That'll be a faceroll.
Well I would use one Gem of Ease in the socket of a 2h ancient weapon (Wormwood seems decent) and the second one to remove the level requirement on Custerian Wristguards (XP for Gold drop). Furthermore, using Hellfire amulet and ring (they both have no level req.) with the highest dmg rolls, and at least one socket to use with a Boon of the Hoarder (ideally lv 50) should help as well getting you asap to Level 70. I guess running vaults from Puzzle Rings or HoA3/Ruins of Corvus, should be the fastest.
For the cube, maybe a Maximus might be good and even fun to use
You can also put a gem of ease into a weapon for your follower. Also give him a hellfire ammy and ring. These will boost the follower's stats (since he won't have an immunity amulet to start). Equip pet to pick up gold (no need for avarice band).
I use the biggest ancient 2 hand weapon with INT, VIT, and socket (i.e., a stat stick), cube wormwood, bracer that gives EXP when picking up gold, and garg ring. Wear hellfire amulet (sycophant) and hellfire ring. For gems, I use ease in the weapon, hoarder, trapped gem. The WD build is haunt, locust, spirit walk, grasp/piranado, dogs and garg. And do a vault run at T6.
This should put you in the mid 50s. Craft a yellow ring with a socket (powerful gem) and a helmet with a socket (EXP gem). Do another vault. Or switch to cow level or fields of misery to rack up kill streak EXP bonus. If not doing vaults, cube helm that doubles helm socket for more EXP bonus.
Considering crafting a level 70 weapon and rolling reduced level requirement to replace gem of ease with crit gem. I kept the weapon I used at the start of the season.
If you plan on solo p-leveling multiple characters, look for the exp ring and helm that doubles gem power that has a natural main stat, VIT, and socket. Use a gem of ease to remove the level. You want natural main stat, VIT and socket so you can reroll the main stat so it can be used by any class. You want VIT because when leveling crit change/damage won't be worth it.
This is what I did last season and I could solo power level a WD in about 35 minutes. This season, I'd probably use RoE instead of garg ring.
If you are just leveling a second WD and willing to spend gems of ease, removing the level requirements from a couple of set pieces would give you the two set bonus. HT two piece + WoD bracer in the cube is one option. Jade 2 with belt that give you and extra haunt + RoE in the cube would also be powerful.
I'd probably pick chest and leg pieces so you can put gems in the sockets.
EDIT: Leoric crown and ring is the better solution (faster leveling, works with more classes).
It's worth noting that some classes have got some OP bracers that add a tonne of % based damage so scales as you level. Barb is best in this position with the SS and HOTA bracers obtainable early on. So if you're relying on drops, Barbs have this advantage.
