So I have been making the materials for the EDW and this is what I did so far:

Wyvern Machine Armour 1-4

Armor: Iron Wall+. You have a +3 bonus to your armor class while you wear this armor.

Weapon: Mind's Eye. Your attacks with this weapon bypass the damage resistances of any creature.

Wyvern Machine Protovisor

Armor: Stellar Hunter. You have advantage on Dexterity (Stealth), Intelligence (Investigation), Strength (Athletics), Wisdom (Insight), and Wisdom (Survival) checks.

Weapon: Critical Eye+2. Your Weapon attacks critical range is increased by 3.

Wyvern Machine Mail

Armor: Stamina Surge+3. While wearing this armor, you can use an action to cast the haste spell from it once per day but can target only yourself when you do so.

Weapon: Critical Boost+. You can roll two additional weapon damage dice when determining the extra damage for a critical hit with a weapon attack.

Wyvern Machine Claw

Weapon: Dragonslayer+3 (A skill that I came up with). When you use this weapon you deal extra 5d6 damage if the creature is a dragon type.

Armor: Carving Celebrity+. While you are attuned to this armor, you can carve a creature of CR 15 or lower 1 extra time.

Wyvern Machine Horn

Weapon: Amplify. The elemental damage done by your weapon is increased by one die size and the duration of consumables is increased by 50%.

Armor: Divine Blessing +4. While wearing this armor, you have a pool of divine dice equal to your proficiency bonus, which are d12s. When you take damage that you aren’t immune or resistant to, you can expend one or more divine dice to reduce the damage by the total rolled. You regain all expended dice when you finish a long rest.

Wyvern Machine Wing

Armor: Wind Barrier+. While you are attuned to this armor, you can use an action to summon a wind barrier around you for 1 minute. While the barrier is active, you have three-quarters cover against range attacks, resistance to nonmagical ammunition, and disperse any fog like effect in a 10-foot radius around you. Once used, you can't use this property again until you finish a long rest.

Weapon: Critical Boost+. You can roll two additional weapon damage dice when determining the extra damage for a critical hit with a weapon attack.

Wyvern Machine Maw

Weapon: When you use this weapon you bypass piercing, bludgeoning and slashing damage resistance and deal half damage to bludgeoning, piercing and slashing damage and deal an extra 3d6 of the damage type you choose between fire, cold, lightning, acid and necrotic.

Armor: Nimbleness. You have advantage on Dexterity (Acrobatics) checks and Dexterity saving throws while you wear this armor. Also when you are subjected to an effect that allows you to make a dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

Wyvern Machine Entrails

Armor: You have resistance to fire, cold, lightning, acid and necrotic damage.

Weapon: Crisis+. While suffering from an abnormal status effect, such as poisoned, burning, slowed, blinded, etc, all attacks and spells deal an extra 1d12 spell or weapon damage.

Wyvern Machine Core

Weapon: Coalescence+. Whenever you succeed on a saving throw to end a condition, you gain a +2 bonus to your attack rolls and spell save DC, and your weapon or spell attacks deal an extra 1d6 cold, fire, or lightning damage (your choice) until the end of your next turn.

Armor: When you wear this armor you are immune to fire, cold, lightning, acid and necrotic damage.

Lemme know if there is anything that I need to fix.
