I have no choice

Loki who was watching the battle between Ace and Hakai suddenly had a bad feeling, and with his experience, he knows that this wasn't just a feeling. 

'That guy Ace is planning to do something, but I don't know what. Whatever it is should be able to harm the pseudo-sage Hakai. Based on what I've seen his most powerful attack might be a long-range one. I do have a spell that might deal with this but the mana consumption might be a problem.' 

The spell Loki was thinking about was a stronger spell than [Deflect] he cast on himself before, it was a spell called [Protection from arrows]. This spell was an ancient one back in his old world the creator of the spell thought that all it did was protect the user from arrows alongside its horrible mana consumption this spell was deemed inefficient. That thought was prevalent until one researcher of magic found the true effects of the spell.
