Add the shield spell to the Artificer spell list.
The Artificer Class Feature Magic Item Savant allow a character to bypass the Magic Item Tier requirement.
In combination with the server rules on Somatic and Material requirements, an Artificer Armorer can perform the Somatic and Material requirements of a spell without the use of their hands while wearing their Arcane Armor, unless there is a costly material component.
Infusions can be learned multiple times. Note that you can only gain the benefits of a specific infusion once at any given time, even if you are able to infuse the effect into multiple items you can wear (ex: you can make two enhanced defense items, but only use one’s bonus at a time).
Once per real life week, you may swap one infusion.
We do not use the feature "Optional Rule: Firearm Proficiency."
Artificers cannot lend out items to people going on quests, unless the Artificer is going on the quest as well.
The Dampening Field ability also allows the armor to become form fitting and wearable under clothing.
