Uniques are optional, here are the BIS chase items if you feel like chasing them: (in order of importance)
Titan Heart LP3 or 4 is nice if you're not feeling tanky enough due to its 15% global damage reduction, 40% health increase; then there's the 40% melee damage bonus... It's the only piece of gear I would likely run even without any LP if the fixed affix rolls were fairly high, it's an insane buff to the build, and at LP0 it's a fairly common drop. This item is on the verge of being necessary by the time you reach empowered monoliths.
Harthenon's Vow is not vital to the build; however, I suggest chasing it to LP3 or 4 early on. This is largely because its drop rate is pretty high and it has several minor bonuses for the kit.
Artor's Legacy would be nice to have at LP4; because it is ridiculously rare, LP3 or even LP2 will be fine. Additional to +1 max companion and 20-30% attack speed... The chance to Chill on-hit will make you a bit more survivable due to the enemy's decreased attack speed.
Vaion's Chariot is probably one of the hardest chase items in the kit, but it will be BIS when you get a chance to chase it. Being faster is a buff for almost every class, to maximize this class keeping Berserker up is fairly important, so it's extra nice to have more mobility to keep travel time between mobs down. It will also buff the damage of your movement skill Fury Leap, meaning you are more likely to proc Aspect of the Mantis. I would easily run this with a good LP2 roll.
Dedication of an Erased Primalist is kind of odd in that a good one can only be attained through Weaver's Will... However, if you manage to find one and it has some good rolls on its upgrades (I received it and it seems to have a very high rate of +1 to abilities), it's probably one of the most important uniques in the kit due to the aspect of the spider working well with Trapper, a passive on the Swipe tree that provides a lot of damage per skill point invested.
Jungle Queen's Chaps of Holding Good for the increased physical damage and it's nice to have the extra potions so you can spam them if you can't get close enough to leech health.
Arboreal Circuit and Ribbons of Blood are anything but necessary and may be better when replaced by good implicit stats on a good exalted ring; however, making legendary equipment can give more bonuses or help with an item that has good affixes and bad implicits. These 2 rings have the most useful fixed affixes for this build. Only run either of these on a good LP4 in most circumstances.
Bleeding Heart is pretty straightforward: you leech more and attack faster. Regarding the bleed, the only spell in your kit is Howl and you don't cast that, your wolves do. As for the regen reduction, you won't have any by this point anyways. Do not run this item sub-LP3 as whatever amulet you'll be running will almost certainly be better. This item is largely for mages and is only here because this build doesn't have any good jewelry-slot items. You may want to keep a good Astrology Amulet over this item.
Some general notes on gearing: (in order of importance)
- You will need 75% on every resistance stat, likely by the time you start on the 2nd or 3rd monolith, this depends on how wide the gap is between your character's level and the suggested level. This is vital, even the end of the campaign can be tough without around 50% across the board.
- Get PrefixMelee Attack Speed on your gloves and weapon, this is a must going into the late game. Not only does attack speed multiply damage, it also allows you to stack your buffs more quickly.
- Getting around 500-700 SuffixEndurance Threshold and 60% SuffixEndurance is incredibly important as you reach level 80+ content. This stat is less important if you stay at the suggested-level, but most people are around 10+ levels under-level by that point. If this describes you, getting 1-shot far too often is in your future and you have no chance to life-leech. Much of this is taken care of by passives, but you will have to supplement the stat regardless.
- SuffixArmor, SuffixArmor, SuffixArmor and Reduced Bonus Damage from Crits, and SuffixStun Avoidance: These are all similarly important, you need to survive long enough to life-leech back to maximum health, and getting stunned will stop you from leeching.
- Ignore regen stats generally, all of your survival comes from copious amounts of life leech on-hit and Titan Heart will cancel regen bonuses anyway.
- DO NOT use on-kill passives or affixes other than Victory Howl. They work, but it completely defeats the purpose of an on-hit build and provides significantly less benefit.
- Get ADDITIVE PrefixMelee Critical Strike Chance bonuses where you can; getting 10-15% base critical chance will allow you to crit incredibly often after all of your passives are unlocked that multiply crit rate. The kit is packed with % increases for critical hits; however, you'll need some additives to boost the usefulness of said passives (added stats are applied, then that total is multiplied by % increased stats).
- The +1 to skills you want are PrefixLevel of Swipe and PrefixLevel of Warcry. The other abilities don't need any +1 other than maybe PrefixLevel of Fury Leap if you're desperate to justify a piece of gear; otherwise, it's a wasted stat.
- PrefixPhysical Penetration is fairly important as you approach 150+ corruption as you don't have a variety of damage types to lean on. A little will go a long way.
- PrefixMovement Speed this is a melee build, bet you can figure out why you will want to move faster.
- Get SuffixIncreased Cooldown Recovery Speed where you can because Fury Leap is very important for 2 reasons: It provides I-frames, mobility, and pull while killing mobs.
- Implicit affixes do not matter on items you plan to slot into Legendary gear.
- All of the listed items below include options other than those that provide resistances; fill any with items that have resistance implicit affixes where necessary. However, if you find a good Astrology Amulet, you may want to use that as reduction of damage over-time is almost non-existent outside of flat damage reduction or endurance.
