Tips for Beating Derelict Masonry Dock

Use Plunge Attacks For AoE Quick Clears

With the Leyline Disorders incentivizing the use of Plunge Attacks, take advantage of this by abusing Plunge attacks to quickly clear through enemy waves and defenses.

This is especially useful for the Furnace Shell Mountain Weasel in Challenge IV as they have a special phase that can only be broken by Plunge Attacks.
