You gain the ability to make two attacks when you take the Attack action, allowing you to strike or cast through your suit with greater efficiency.

You know mending and mage hand, and can use them with a variety of clever gadgetry and improvised devices.

You can restore spell slots by tinkering with infused items during a long rest, and you gain access to the artificer spellcasting feature using Intelligence as your spellcasting ability.

You have a number of infused items, can create magical infusions from a list of artificer infusions, and can maintain multiple active infusions at once.

You gain the Armorer specialist, along with proficiency with heavy armor. You can use a suit of armor as an arcane armor, integrating it with your body or your custom exosuit. It can be your spellcasting focus, and it can be donned or doffed without assistance.

Choose the Guardian armor model. You gain thunder gauntlets as weapons, and your armored suit can impose protective control on nearby foes, making you harder to ignore in battle.

Your proficiency bonus is doubled for any ability check you make with a tool you are proficient with, reflecting your obsessive craftsmanship.

You can add your Intelligence modifier to initiative rolls, and when you or a creature you can see within 30 feet fails an ability check or saving throw, you can add a bonus to the roll a limited number of times per day.

You can infuse your armor in specialized ways, granting additional benefits to your suit and any infused parts of it.

You can create and use one spell-storing item, allowing repeated use of a 1st or 2nd-level artificer spell you know.

Your magical item crafting becomes more efficient, and you can attune to more magic items than most adventurers.

You gain an additional attunement slot and can ignore class, race, spell, and level requirements when attuning to magic items.

Your Guardian suit gains Perfected Armor. When you activate defensive systems, you can force creatures near you to protectively focus on you, and your suit's control systems become even more formidable.

You have created a second identity and can convincingly pass as that person, using forged documents, false contacts, and a practiced story when you need to disappear or mislead others.
