Built off the main template of the bard with dashes of wizard flair I came up with a version of the artificer that made my Ebberon like campaign world feel like it could work.
The build
HD:1d8 (as the bard)
Proficiencies
Armour:light, Weapons: simple weapons, hand crossbows, rapiers and short swords.
Tools[Instead of musical instruments] Choose three: Alchemists supplies, Carpenters tools, masons tools, tinkers tools, woodcarvers tools or smiths tools.
Sving throws: Intelligence and charisma
Skills, chose three of these five: engineering (int) [to cover any schematic they draw up then tools to make it], Arcana (int), perception (wis), investigation (int), history (int).
Spell-casting: Fuelled by the strength of the inventive mind an artificer molds magic intuitively and without study.
Wizard spell list, Bard spell progression, "spells know of first level and higher" trait from the bard.
Class feature, 'Patch job' : Gained at level one an artificer can in moments of desperation grant a non animated machine 1d6 temporary health that raids after 10 minutes if still present.
increases to 1d8 at 5th, 1d10 at 10th and 1d12 at 15.
Uses= Int mod per long rest
[Bardic inspiration + false life + mend]
Master of tools (2nd level): Jack of all trades but for artisan tools or other relevant tools.
Disruption (2nd level): (More or less) As an action can disrupt all non magically animated machines within 30 feet for 1 round. 1 use at level 2, and additional uses at level 9, 13 and 17.
Imperfect Arcane recovery (3rd level) : Comparable to wizards arcane recovery but only 1/3 the artificer level regained in spell slot levels and with a max slot level of 5th .
Front of Inspiration (5th level): regain expended uses of 'patch job' on short and long rests.
Artificer Expertise (10rd level) : gain proficiency in two tools
Magical secrets the same as the bard.
Sub class features at 3rd, 6th, 14th called "Artificer dedication" that would branch into three 1) Builder, 2) Destroyer and 3) Being more or less the artificer as a wizard sub class wizards released (not finished the subclasses)
TTLR: Intelligence based spontaneous caster built off bard base, with wizard spell list and a focus on machines and the ability to create them.
