"Magic Yin and Yang"
"Magic Holgro"
"Magic Sargatanas"
I do not approve of these names.
Dual Blade - Sargatanas combined with Lifestealer blade! Combines both effects from both swords!
And even the craziest one - Triple Sword! Sargatanas & Lifestealer & Santoryu! I'd be the luckiest one if some day I'd be able to got it!
Or even the maddest idea - Quadriple sword!!!!!! Sargatanas & Lifestealr & Santoryu & Excalibur !!!!
In no way is Aero going to implement these crazy stuff. There's a cap of 500 characters for an item description, good luck cramp every special thing into that limit. Balance issues aren't a problem (Omega Set began as a crazy idea of mine, too).
