This build feels really nice to play, the combination of Rampage and Maul while mapping feels super smooth.
Maul,Swipe and Earthquake can be scaled with PrefixIncreased Elemental Damage.
Druid is quite tanky through the use of a number of passives – Aspect of the boar,
You get a Thorn Barrier 1/1 for even more damage reduction.
Crits are super satisfying to play with.
This build is very Melee (Swipe, Maul, Earthquake). Earthquake means you don't have to be on top of the boss all the time, but you do need to be there at some point.
Keeping up Aspect of the Panther 5/5 with Swipe is important and means you really need to be in melee range most of the time.
There are is one mandatory unique in Bhuldar's Wrath. It's not that hard to farm but it is still required. Tears of the Forest can be replaced with Spriggan Form but it does cost you a skill slot.
Much of your recovery is based on leech. This is mostly okay since you're hitting things, but in some cases is really bad.
PrefixIncreased Elemental Damage is only on rings and amulets, so in this case we only have two direct items slots we can get it on (unless you're using Spriggan Form in which case you have three)
