'Oracle, is there a way for me to put an end to this as swiftly as possible'.
Orun is having a hard time thinking of ways to put down an enemy that turns into smoke to recover itself after being hit.
The plan he came up with, to have it exhaust its mana. That was a well thought out plan that is only useful in long term battle.
It requires time and patience to accomplish, and time happens to be the one thing that Orun is short of at the moment.
A gate leading to world destruction is a development that has to be avoided at whatever cost possible.
Orun thought of using his wood skill to trap it once it turns into an hazy smoke, but he realized that there is a lot of flaw in that plan.
No matter how confined and sealed he makes the wood like, there is still a chance for the hazy smoke to come out by merging itself into the wood and flowing out through it.
Like how breeze blows into a tightly sealed object, starting with entering the object and coming out from the other side of it.
