Current Cantr battle system
Terrorizing a town alone
If you have several locked buildings, you can lure people into them and lock the door. But this only works once or twice, after that people become wary.
Hiding in a building/buildings allows you to snipe at people with relative safety, but in big towns, someone is always awake, so you must be sure not to come out more than once in an hour. Because if you get hurt, you can't get through shields anymore, especially if you're a poor fighter.
If you have several locked buildings, but the enemy has crowbars, you should keep track of how far the lockpicking has advanced and which locks have been broken. You mustn't run without a plan. Instead of running from building to building, always return to your "base" after making the move, and wait.
If you're going to reply to people, write it while inside, then run outside, copy-paste, hit enter and run back inside. Or better yet, slip notes. Actually, communication is just a way of making you stand outside long enough to be hit or dragged.
Be prepared to kill people if they don't meet your demands. Target the ones most likely to carry important keys. Killing helpless youngsters might help in getting a point through but then everyone is gonna hate you and fight even harder.
Preferably you should have a bunch of healing food. But a situation like this happens only in two cases: 1) a town official dies and drops all the keys, you're first one to grab them and 2) you
are that town official, gone nuts and wanting revenge. In case 1, there won't be any planning, you either have healing food or you don't. If you don't then hopefully no one else has either. In case 2 there might be more planning involved. But you might as well invite people indoors for a party and then lock-em up.
Battle on roads
Basically, the one with the fastest vehicle wins. But that's not quite true, even numbers do count. You should plan it so that if the town you're attacking doesn't know you're a threat, you must calculate when travelling progress happens, then stay idle until like ten or five minutes early, then hit your target and flee. I'm not sure if it's possible to go out of range in one hour with a bike. So it's better to have a motorbike.
If you're attacking only a small group of people or a single person, you could try dragging them into a building (provided that you're strong enough) so that they don't know which way you left. That should give you enough time to escape. But most likely you're gonna be too tired to succeed alone. Dragging first, then hitting might work, but make sure the building doesn't have a lock or according to Murphy's law, the only person with the key is gonna be awake just as you step in.
Piracy
If you're close enough to the shore then you can dock in one turn. But if it's a longboat then it's gonna take three turns anyway, no matter if you're right close to it. It's kinda backwards... With a raker you can dock like anywhere that's kinda close, but you'll end up in a harbour so there's a chance someone's gonna lock the door if you start breaking havoc. I haven't sailed a sloop but that might be a good option. Or hell, the darters are kings. The darters are invincible. Nothing docks to those buggers. So all you gotta do is move swiftly while on the shore.
If you're not a known pirate and if you can't dock instaneously, to lower doubts you might want to drop your crowbar and weapon on the deck, thus anyone looking at you will think that's just a trader. You could sit there watching silently for the three real-life hours, taking notes of who's active, if anyone, what weapons do they have, if they're tired, wounded... It might be nice to know if there's any boats in town, especially dinghies, but if you want to pretend to be a total sleeper then naturally you cannot step off the boat.
When there's ten or five minutes to travelling progress, it's time to move. If you're just gonna hit people then you don't even have to step ashore, you can do it from the boat because even swords are ranged. Neat, huh? But if you want loot then naturally you gotta venture it. No one's gonna suspect anything once you step ashore. But once you start running around buildings, you can be damn sure they're gonna start screaming. Only pick what you need. Make sure to get outta there before the time limit. Since here's the trick, once you undock, set course that's not a round ten or 5 ended number. So they'll have a hard time following you. And you'll have an hour's lead because no one's gonna have time to react before turn progress. Otherwise if they undock to the same direction, they can dock to you straight away.
One good thing for looting a big town would be to have henchmen, but you'd have to give them keys because if you leave the boat open then someone's gonna hop in and undock. Also make sure that none of them will abbondon you. You abbondoning them is a choice but don't tell that to them. Anyway, it would be good to know the amount of buildings in advance, and divide them between the people. Then you also gotta make sure everyone is awake and knows the plan, knows to move on the right moment without whispering. No whispering while docked, 'cause that's suspicious.
Sea battle
Cantr is so ingenious that if you can dock to someone, they cannot dock to you. Because it's all about sizes. Hah. So if you have a big boat, you just run the hell away from anything that could dock to you, and if you're in a small boat, dock, hit, undock, follow direction. Or you might leech onto them if you have enough healing food to waste.
If you're planning to dock to another boat then be sure to ride right on top of them, even if they were stationary, because chance is they might have a dinghy and dock to you while you're in process of docking to them. And the mere attempting to dock somewhere usually qualifies as piracy. Though if you got someone docked to your boat, someone with big weapons while you have none, you better be nice to them and just hope they go away.
