Clockwork Artificer

Forgoing the larger projects of their cousin subclasses, the Clockwork Artificer focuses almost entirely on smaller creations and minor enhancements. More in tune with toymakers than siege smiths, they find their pride in the trinkets that their allies wear and the gadgets that make combat just a little bit more hectic.

Tool Proficiency - 3rd lvl

You gain proficiency with Painter's tools. If you already have proficiency with these, you gain proficiency with one other type of artisan's tools of your choice.

Stabilizer - 3rd lvl

You've discovered a method of keeping magic items stable in close proximity, which allows you to hold more enchanted objects at once. You may now have 1 extra Infusion active at once. In addition, your capacity for attuned items increases by 1.

Clockwork Magic - 3rd lvl

You always have certain spells prepared after you reach particular levels in this class, as shown in the Clockwork Spells table. These spells count as Artificer spells for you, but they don't count against the number of spells you have prepared. (3rd level - Shield/Magic Missile, 5th level Branding Smite/Shatter, 9th level Hypnotic Pattern/Conjure Barrage, 13th level Death Ward/Greater Invisibility, 17th level Cloudkill/Passwall)

Overclocked - 5th lvl

You've figured out a shortcut in your Infusion that allows you to imbue more power into it. Choose one Infusion when you gain this feature. Permanently double the effect of the Infusion you chose.

Clockwork Combat - 9th lvl

You've begun to recognize the pattern that the game pieces move in, and gain insight into the initiative count. Once per turn, you may take an extra Reaction.

Biological Mechanism - 15th lvl

You've come to the understanding that life is a giant, complicated machine, and you can see the inner anatomical workings of most creatures. You gain proficiency in Medicine if you were not already proficient, and your proficiency bonus is doubled for all Medicine checks you make. In addition, any healing you take is doubled.
