On manual repairing of your Explosion Blade (or other expensive item)

Could it be some glitch in the game or was it just another fragment of my wild imagination? Afraid that my super expensive Explosion Blade would be broken, I tried to manually repair it in the game but to my surprize, it goes down to 25 durability, pffffft!

So I had to repair it on the Forsaken Mu’s Control panel and had to pay 20,000,000 Zen, which is by the way overflowing but not so useful in the game aside from this online repair, and buying pots and item combination in the Chaos Machine. I was informed that this only happens with the Explosion Blade and not on any other expensive (or non-expensive) items from the online store.

If you happen to be a Magic Gladiator, tell your humans not to repair this sword manually during the game or he will have to regret it forever when it goes pffffft and got broken. Instead, go to your online control panel and repair it in the Character Options.

What’s more interesting is that its full durability shows 255/157. Cool, eh?
