Just as the title explains, there will be another boat section (Similar to sails/hulls/figureheads) that adds a certain utility to a ship.
Examples:
Water Barrel:
Makes the ship immune to fire/magma dmg OR
make it more resistant to heat-based attacks
Emergency Rowboat:
Adds a rowboat that you can cut off and escape with
Move Grappling hook to utility:
Self-explanatory
Lava Barrel:
Makes the ship immune to cold-based after effects, like frozen, but sets you to ship on fire for a couple of moments Or
make it more resistant to cold biased magic
First strike:
Your first cannonball shot does more damage. Refreshes when you repair your ship
Meat Freezer:
Adds a storage space for food to not spoil
Cannonball Storage:
Increases storage for cannonballs
With enough explosion magic, anything is possible… atleast in the realm of turning things into craters or removing all evidence that they ever existed.
i made a suggestion a while ago that no one really cared for. ill use part of it on this…
make something (in my suggestion was water magic) that camoflagues your boat in the water so sharks dont see you (sharks attack small boats
