Hi, I have finally mostly gotten regeared after my first disastrous attempt to build up an island base off the coast of a swamp near a plains biome. I need a base somewhere along this swamp coast to prepare to fight Bonemass, but I'm finding it tricky to find an area that isn't swarming with enemies or won't soon be.
In the absence of battleship fire support, any tips for establishing a beachhead on a hostile swamp coast?

Just build a portal to your main base or home, prepare everything there and once you ready you can just go to Swamp using portal. It's a much easier than building a new temp base just for one boss.
