Out of curiousity, what's the largest scale battle that we've had in LEW to date? The players in A Clash of Earth and Sea are in the process of recruiting a large force of Merfolk (40 or so NPCs with the 5 players) to aid in their battle with the Merrow. It's been speculated that the Merrow may empty out of the dungeon in response and meet their force in battle....
Merrow sized longspears, merfolk tridents, and the equivalent of shark infested waters! Not for the faint of heart!
