Suit, that is. A Crysis Suit.
Currently I am in an Eberron game, and I have had the fortune to get the opportunity to play as an artificer. I am level 6 at the moment, and it is great fun. But right now, I have little creativity after making my latest creation (Gloves that give one element type to a melee weapon. Ex: Frost, Flaming, Corrosive, Shocking). Instead of coming up with something from my own head, I thought "Hey, why not make something from a video game?" Then I went deeper, thinking "Let's make an armor, not a trinket or weapon this time." I came up with the Crysis Suit.
I know that the suit has 3 modes: Stealth, Armor, and Strength (Which is kind of automatic). However, I have no idea how to go about making this item. I am open to suggestions about how it should work. Right now, as the beginning stage, I am thinking about giving it situational sets (Barkskin in combat, Cat's Grace / Lesser Invisibility for cloak, and Bull's Strength when using heavier weapons / items). Any tips on how it should begin and how it should progress are welcomed. This is, after all, just an idea.
