A creative solution

Introduction

Pierce still needs help to collapse the tunnel just the same, I guess. Evidently I won't ask you to do it, because as already said, it is extremely dangerous. But I might have a creative solution. It will be enough to use corrupted therianic energy, to create a living-dead ... but a simple zombie will not do. Go talk with Torvalsia at the White monastery. She will tell you what must be done next. It is unnecessary to tell her that I am dead ... it will complicate everything.

Cunclusion

Create a living-dead resistant enough and sufficiently capable to place an explosive underwater? I might have an idea, yes.
