It is possible to study the weapon set of you opponent, and change your equipment accordingly. While I've not done this yet, anyone that has a fairly strong light attack, and you get the parasol which is down to 70K this minute and who knows tomorrow.
Effectively, with burrow and sink you almost get two turns nearly free to attack.
The combination of the wing scarab and a makeshift ships hammer can do wonders on some opponents.
P.S. Got my Parasol today, as a prize. I'm thinking about selling today at 25K.
Also, in 1 player is a particularly nasty weapon out there known as the Prismatic Mirror. It will destroy you, as it works with reflected icons and your shields will fail. The key, is attacking only with physical. I found, that two "Swords of Knowledge" are perfect, while the attack is week it is unreflected, and your added defense is useful.
