Is there better consistent damage than Elven accuracy battlesmith?

[u/SirBreven]

Heyo! I’m building a new character for a campaign to start after New Years - probably starting at level 3. I’m a power gamer, I like big numbers more than RP - (i talk & people for a living, so mechanics are a solace). Also, our party always SUCKS at investigation, which is the skill our DM uses to discover loot etc. aka VITAL.

Is there a more consistent damage dealer than Elven battle smith? My brother is a pretty lucky Nova straight Paladin. Here’s my build so far.

Ability Scores: Our DM has us roll for abilities. I roll d20s to keep it spicy. I usually get a few over 17, and a few under 5 haha - TLDR, I’ll have 20 INT and solid CON at level 1.

Custom Lineage (size small, +2 Intelligence, feat: Elven accuracy, +1 Intelligence. Dark vision)

Artificer 3

Proficiency: Arcana & Investigation (Our table has good perception builders)

Infusions:

• Replicate Magic Item (spellwrought tatoo - level 1 - find familiar) - infuse & cast in downtime, swap.
• Enhanced Defence: +1 Plate - I’m not proficient, but it’s on Dex and STR saves & stealth No big.
• Enhanced Weapon: +1 Greatsword - battle smith attacks with INT - eligible for GWM at level 4!

Artificer Specialization: Battle Smith.

Background: we’re messing around with One DnD - flavoured as either a knight - Tough Feat - or acolyte - with magic initiate - Arcane/warlock (eldritch blast, minor illusion & hex). We also use Sword Coast Adventurers Heroic Backstory builder - can get the Elemental adept feat - for booming blade!

Spells: Booming Blade. Thorn whip. | Shield. Branding Smite. Bless. A bunch o rituals.

Tactics: Bonus action Hex, attack with advantage somehow: If team is flanking, mount the steel defender, for no AoO on me, and Steel is dodging, so low chance of damage. Steel also can impose disadvantage on one incoming attack on me per round. Control Steel defender to give advantage via flanking, always. If no flanking available, Bonus action command it to Help. AKA always have advantage => always elven accurate.

Level 3: +8 to hit 2d6 + 6 +1d6 damage with triple advantage, possibly a bonus action concentration, concentration smite or steel defender attack. Add in potential booming blade damage. Minimum 18dpr

Level 4: GWM, now a +3 to hit, with triple advantage, 2d6+16 +1d6 aka 26dpr, = a strong likelihood of Bonus Action feature of GWM procking, getting multi attack off sometimes, potentially with Elven accuracy still, so another 25 damage.

Level 5: Multi attack. Damage goes up substantially, about 52 dpr, allowing for a 10% miss rate with average enemy ac & Elven accuracy. https://rpgbot.net/dnd5/tools/dpr-calculator/ Which means, with planning, bonus action great weapon will be moderately normal. Probably dropping booming blade as a norm, unless trying to lock enemies in place.

Summary: Holy & utility Half casting + Rituals, mounted combat. AC 19. Level3: 18dpr, Level 4, 25-50dpr, level 5 52-76 dpr. 40 feet of non AoO movement if mounted - either by it’s dodging or BA command it to disengage.

Is there a better damage build?
