ONE BAR HEAVY ATTACK NECROMANCER SUBCLASS PVE DPS BUILD

• Ulfsild's Contingency (Shock, Lingering Torment, Force) - your source of crucial Empower buff, which increases damage done by Heavy Attacks by 70%. Since Ulfsild's Contingency is a Mages Guild skill, it will trigger the Might of the Guild passive, which grants you Empower for 10 seconds. It also deals decent damage in an AoE and grants you Minor Force buff, increasing your Critical Damage by 10%. Ulfsild's Contingency is delayed until the next skill cast but whenever it's needed you can activate it early by bashing your enemy. If you cast this ability as you're finishing your Heavy Attack, the Empower you gain from it will start working just in time to boost the final tick of that Heavy Attack you just finished
• Grave Lord’s Sacrifice - this ability summons a skeleton which leaps at you, increasing your damage done with Necromancer abilities and DoTs by 15%. It's important because the channeled part of your Heavy Attack is considered a DoT. It will also generate a corpse for Detonating Siphon and trigger Grave Lord passives
• Merciless Resolve - an ability that will cause your Light and Heavy Attacks to generate stacks. You can spend 5 stacks to fire a powerful arrow that also heals you if you're in Melee range. It also grants you Major Savagery and Prophecy
• Detonating Siphon - an ability that connects you to a corpse with a tether which deals a lot damage over its duration and explodes at the end. It also passively increases your damage done by 3%
• Banner Bearer (Magic, Cavalier's Charge, Berserk) - increases your Magical damage done by 6%, grants Weapon Damage based on your movement speed and grants Minor Berserk, increasing your damage done by 5%. If your base class is Necromancer, you can instead use the Class Mastery signature script, which will be a slight DPS loss but it will grant you increased survivability. You can also change the Berserk script to Heroism if Minor Berserk is being provided by your supports.
• Soul Harvest - a cheap ultimate that increases target's damage taken from you by 20%. Having it slotted will also cause you to regain 10 Ultimate whenever you deal a final blow against an enemy
• Concealed Weapon - an ability that will passively grant us 15% movement speed, which will grant us 90 Weapon and Spell Damage thanks to the Cavalier's Charge script on Banner Bearer

• Whenever you need to slot situational skills, replace Detonating Siphon
• Elemental Blockade - your source of Off Balance if supports aren't providing it. It requires enemies to be Concussed, so you'll have to use Shock enchant to proc it or rely on your teammates for that.
• Elemental Susceptibility - use it as your source of Major Breach whenever you're assigned to mechanics that separate you from your group, like for example portal in the Nahviintaas fight, Reef Hearts in the Reef Guardian fight, bridge in the Taleria fight, etc.
• Hurricane - an ability that deals decent damage. increases your Weapon and Spell Damage through the Expert Mage passive and grants you Major Resolve, increasing your armor. Usually Major Resolve should be provided by your tank, but if it isn't, you can use Hurricane instead and it's only a slight DPS loss compared to Detonating Siphon because Hurricane itself deals really good damage
• Critical Surge - a very strong self-heal. Use it when you need a self-heal because you're assigned to some duty which puts you far away from your group, or if your healers are bad. It also increases your Weapon and Spell Damage through the Expert Mage passive

Priority List

I don't use a static rotation so this is just a list of priorities. Simply recast abilities when they run out and follow this list of priorities when there are multiple things to refresh

If you're tracking the Off Balance debuff, you should cancel your Heavy Attack when there's around 1-2 seconds left on the Off Balance Immunity. This way the next Heavy Attack you start will finish its channel during Off Balance and you'll be able to fit 3 Heavy Attacks during a single Off Balance window

• Use Ulfsild's Contingency if your Empower is out or if it's going to run out by the end of the Heavy Attack you're channeling
• Use Grave Lord’s Sacrifice when there's less than 4 seconds left on it
• Use Soul Harvest whenever it's ready
• Use Detonating Siphon (you only have 5 seconds until the corpse from Grave Lord’s Sacrifice disappears, so if it's about to run out, using Detonating Siphon before the corpse expires is top priority)
• Use Merciless Resolve if you have at least 5 stacks
• Use Ulfsild's Contingency as a filler
