Perfected Armor
At 15th level, your Arcane Armor gains additional benefits based on its model, as shown below.
Guardian. When a Huge or smaller creature you can see ends its turn within 30 feet of you, you can use your reaction to magically force the creature to make a Strength saving throw against your spell save DC, pulling the creature up to 30 feet toward you to an unoccupied space. If you pull the target to a space within 5 feet of you, you can make a melee weapon attack against it as part of this reaction.
You can use this reaction a number of times equal to your proficiency bonus, and you regain all expended uses of it when you finish a long rest.
Infiltrator. Any creature that takes lightning damage from your Lightning Launcher glimmers with magical light until the start of your next turn. The glimmering creature sheds dim light in a 5-foot radius, and it has disadvantage on attack rolls against you, as the light jolts it if it attacks you. In addition, the next attack roll against it has advantage, and if that attack hits, the target takes an extra 1d6 lightning damage.
We already gave this at level 9 (just nerfed). I'd simply make a "perfected armor mkII" that powers up those 2 effects to their original values.
