There exists a POWERFUL WEAPON in a locked CHURCH in [REDACTED].
[REDACTED] can help you access the CHURCH...or you can make your own way inside.
It seems unlikely that any of the unwholesome things which endanger the HERMIT would fare well against the gleaming tip of this otherworldly weapon which inflicts damage based on your FORFEND score.
Most lesser enemies will freeze at the sight of and/or collapse instantly under the heft of this polished blade, but the strongest of foes all have deep reserves of HIT POINTS and only by effectively wielding the weapon and striving for ever higher FORFEND can you defeat them.
