Damage Combo

Lune Archmage Build

This has been on my to-do list for a very long time. As many people know, Shadow Magic is that perfect sounding theme, which gives the dark vibes, a cool summon and easily accessible Darkness icon bg3Darkness. The reality?

Well, it’s a bit nuanced. The Hound of Ill Omen icon bg3Hound of Ill Omen is cool, but it has limited HP, and its effects have fixed Spell Save DC, so plenty of optimisation will be needed. However, what I really liked is that it can safely stay in the Darkness icon bg3Darkness which gives him a safe haven and an easy source of Advantage icon bg3Advantage.

To top it off, it has a cool gimmick – Splinter Shadow icon bg3Splinter Shadow, allowing it to create multiple versions of Nimbus for a few turns. They are not strong, but 2-3 of these also start splitting from themselves, and each of them casts Umbral Tangle icon bg3Umbral Tangle for a little damage. Besides damage, it can also root enemies in place, making their movement more difficult, and your allies get Advantage icon bg3Advantage.

With this build I really want to lean on the “shadow” aspect. For this, not only will we use Shadow Blade icon bg3Shadow Blade extensively, but also Oathbreaker subclass, to gain more proficiencies, a few powerful spells and Divine Smite icon bg3Divine Smite for extra power when you hit with your blade.

Of course, this is a sorcerer, so you are very powerful caster, and whether you choose to lean more into a shadowy playstyle, or just use up spell slots for high damage spells, you will always be satisfied by the results and what the build can do.

Following the guide and a few tips: Build Overview covers the quick aspects and choices for the build - gear, levelling, etc. The progression by Acts cover the build in great detail, from spell selection to how utilize various features. Be sure to check the equipment sections for gear options and explanations. I also add additional section for build maximizing like consumables, illithid powers and others.

Class Contribution

The build consists mainly of 2 classes:

  • Constitution saving throw proficiency to help maintain spell concentration when being hit.
  • Access to good defensive spells, like Shield icon action bg3Shield​ to improve survivability.
  • Access to cold and lightning spells – Lightning Bolt icon action bg3Lightning BoltCone of Cold icon action bg3Cone of ColdChain Lightning icon action bg3Chain Lightning, etc.
  • Access to a variety of cantrips like Friends icon action bg3Friends, which are especially useful if you are the main character, as you can win over the dialogues.

Fleet of Foot - your movement speed is increased by 1.5m.
Almost any build can benefit from the extra movement speed. I think the same is here, so I definitely recommend this option

Gear Recommendations

Codex:

Here are some recommendations on how to follow the gear picks: I recommend checking the Item Checklists or Interactive Map, depending on which is easier to use for you. This will help you track which items and when you should pick them. Gear for each slot is listed Best -> Worst. Generally, this means that you would start with lower gear recommendations (as they are available earlier) and upgrade to higher ones. However, in some cases, the best items can be obtained early, like Titanstring Bow, and some others. I mention Stat Sticks in caster and ranged builds. These are items that you do not use directly (like Club of Hill Giant Strength, Knife of the Undermountain King, The Dead Shot, etc.), but their bonuses still apply to other weapon attacks or actions. If an item is taken by another character, use the one with lower priority or even those from previous acts. If you want to have the best items for all builds, this will require planning, which is not for everyone.

Main Hand

Melf's First Staff

This is the go-to caster weapon in Act 1 with +1 Spell Save DC.

Alternative

Shadow Blade

This weapon, for now, is optional, as you might not be inclined to always fight enemies with melee attacks. However, when in Darkness you gain an easy advantage, so the damage + hit chance is pretty good.
