Just couple ideas:
Danger Sense: Counter lucky shot by predicting the shot, thus dodging.
Ship Repair: Advantfe of Dog Wand. As our ship hulls are wood and can summon wood. We can fix our battered ships at sea. Just accelerate/induce haul growth to repair.
Land Ship: My take on steam engine water wagon. Has four huge wheels with blades. Armor. Steam engine with exhaust jet for blasting, mobile hybrid Cannon and sluts for bows/fire balls. Could double as troop transport or invest in a Sister unit as a ancient apc (hey it exists. Trojan horse. Just combat efficient.)
Danger sense is new tech, but they have it so maybe we can get a cheapening from observing. I prefer living magic, we can make crystal shields that observe and defend autonomously. Their antimagic is getting more range, but it is still very short ranged, and we should be able to make a magic syphon that acts as a barrier against it, and it would stop prediction also.
I like transforming still-living trees(Something coastal for salt-resistance) into ship hulls, for the same effect, but more awesome...
sluts for bows/fire balls
Would be crippling effective against Moskurg, but we don't want to go there...
It would be nice if our cannons could be used to take out their ballistas. Or their mages. Or their commanders. Right now it sounds like we can aim them, but like all smoothbore weapons, they don't fly straight.
Is mundane accuracy going to help with that? We can't even see them until we are inside of their preferred range. I figure that we are aiming at locations rather than materiel...
