ONE BAR TWO HANDED HEAVY ATTACK SOLO BUILD

• Ulfsild's Contingency (Shock, Lingering Torment, Force) - your source of crucial Empower buff, which increases damage done by Heavy Attack 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.
• Deep Fissure - deals a lot of damage per cast, applies crucial Major and Minor Breach debuffs and provides 5% Critical Damage through the Advanced Species passive
• 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
• Dizzying Swing - an ability you'll use to apply Off Balance to your enemy. Off Balance is a 7 second debuff that increases damage taken from Heavy Attacks by 70%. After it expires, the enemy is immune to Off Balance for 15 seconds.
• Hurricane - your source of Major Resolve which is a crucial defensive buff. It also deals decent damage and grants Weapon and Spell Damage through the Expert Mage passive.
• 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.

Merciless Resolve is the first skill that has to go when you need to slot something situational, unless the situational skill specifically says that it's replacing something else

• Critical Surge - extremely strong self-heal which you can slot when you need more consistent healing
• Resolving Vigor - a burst heal which is better than Critical Surge in fights where there's a lot of incoming damage in a quick burst. It also grants you Minor Resolve, increasing your armor. It can also be used in fights with invulnerability phases where you can't heal with Ring of the Pale Order, Reaving Blows or Critical Surge
• Ulfsild's Contingency (Shock, Gladiator's Tenacity, Force) - a different combination which uses Gladiator's Tenacity script instead of Lingering Torment, which trades the DoT for an 8% damage reduction. Use it in more difficult fights.
• Trample (Physical, Lingering Torment, Off Balance) - an alternative source of Off Balance which could replace Dizzying Swing. Thanks to the DoT component it ends up dealing more damage than Dizzying Swing, but the 1.5 second cast time makes it difficult to pull off in fights with lots of stuns and staggering mechanics
• Silver Leash - a chain ability that you can slot in trash packs to stack enemies and get through them faster
• Revealing Flare - slot it for more difficult fights where you need more damage mitigation. It's a skill that passively grants Major Protection, reducing your damage taken by 10%. It will also trigger the Magicka Aid passive, which increases Magicka Recovery by 10%
• Precognition - an ultimate that breaks you out of some otherwise unavoidable stuns, you'll need it to get around some mechanics which are otherwise impossible or very difficult to solo, like for example Inferno's Hold in Zaan the Scalecaller fight
• Ball of Lightning - an ability that teleports you forward. Use it in fights where you need more mobility or in fights where this teleport allows you to invalidate some mechanic

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

• Use Ulfsild's Contingency if you have no Empower or it has less than 2 seconds remaining
• Use Soul Harvest
• Use Dizzying Swing if Off Balance is ready
• Use Deep Fissure
• Use Hurricane
• Use Merciless Resolve
• Use Ulfsild's Contingency as a spammable

Pre-buff

These abilities can be pre-cast before entering combat
