On my solo character I docked my karve off the shores of a swamp which contained a lot of crypts and to my surprise Bonemass as well. Docking near a beachside crypt I quickly built a base on top of it (immune to abomination attacks) and then made a raised earthen wall around my base so only wraiths and the occasional ooze could get in.

My boat eventually got beaten up by a stray abomination but thankfully I managed to get back all my resources from that.

Abominations are easy to axe down when you have the high ground when it comes to indestructible crypts or swamp trees. Or using a surtling fire geyser to your advantage. Root armor is extremely useful for both the swamp and plains due to poison resistance and pierce resistance.
