PC on Crystalline (12^50), Shield (-3, 10%) & Brute Sword (14% enchanted, req. 8)

Hello,
I need PC help with the following items:

Crystalline Sword of Defense [PURPLE]
Slashing Dmg: 15-22 (req. 11 Swordmanship)
Damage +12% (while Health is above 50%)
Armor +5

Skeleton Shield [GOLD]
Armor: 16 (req. 9 Tactics)
Received damage -3 (Chance: 10%)
Health +35 (while enchanted)

Furious Brute Sword of Defense [GOLD]
Slashing Dmg: 15-22 (req. 8 Swordmanship)
Damage +14% (while enchanted)
Double adrenaline on hit (Chance 8%)
Armor +5

Also, since the Crystalline sword is a bit rare and I plan to sell it, would it be wise to use some top upgrades on it like 10/10 penetration & +30 health before selling it or will it be just a waste of money (plz note it is a purple not gold sword)? I appreciate all help, thx in advance.
