From what I could tell, the 2019 UA Artificer lacked the cool factor in various areas and it was rather limited when it came to crafting, so I made the following modifications.
Am I missing anything that could result in this becoming much more powerful compared to other classes, rather than just increasing the artificer's damage output a bit and increasing the versatility when it comes to crafting? Is this modified artificer unbalanced?
Only the changed features are noted below:
Starting at 3rd level, your proficiency bonus is doubled for any ability check you make that uses your proficiency with a tool. You can craft anything for which you have the required tool proficiency in the quarter of time required for half of the price.
Starting at 5th level, you can use a cantrip as a bonus action, whenever you take the Attack action on your turn.
At levels 4, 8, 12, 16, and 20, the homunculus gains +2 to its Dexterity score.
Acidic Spittle. Ranged Weapon Attack: +2 to hit, range 30 ft., one target you can see. Hit: 1d6 + Dex acid damage. At levels 5, 11, and 17, the damage increases by 1d6.
Buoyancy. The target gains a flying speed of 10 feet for 10 minutes. The speed gained is increased by 10 more feet at levels 5, 11, and 17.
Resilience. The target gains a number of temporary hit points equal to 2d6 + your Intelligence modifier. At levels 5, 11, and 17, the temporary hit points gained increase by 2d6.
Flamethrower: The turret exhales fire in an adjacent 15-foot cone that you designate. Each creature in that area must make a Dexterity saving throw against your spell save DC, taking 1d8 fire damage on a failed save or half as much damage on a successful one. The fire ignites any flammable objects in the area that aren’t being worn or carried. At level 5,11,17 the fire damage increases by 1d8
Force Ballista: Make a ranged spell attack, originating from the turret, at one creature or object within 120 feet of it. On a hit, the target takes 1d8 force damage, and if the target is a creature, it is pushed up to 5 feet away from the turret. At level 5,11,17 the damage increases by 1d8 and the push effect is increased by five feet.
Defender: The turret emits a burst of positive energy that grants itself and each creature of your choice within 10 feet of it a number of temporary hit points equal to 1d8 + your Intelligence modifier (minimum of +1). At level 5,11,17 the temporary hitpoints granted increase by 1d8.
