Hey, I'm relatively new to Unreal World, and I was wondering if any of you guys could give me some tips and advice in Combat, since I kinda struggle with It sometimes, and had died several times not knowing what I did wrong or what I didn't do, all I want is the basics of combat, things to keep in mind in combat and very useful stuff in combat, I'd really appreciate your help.
Welcome to the game and the forums!
As per your own experience so far & replies in this thread, combat indeed is very risky. As already mentioned, the problem is, even with best possible armour on your character, and a huge army of your own beside you (=hired villagers acting as bodyguard), you are still fragile so just one single arrow to the eye (which cannot be armour-protected) and your game is over.
With the ever present death risk do not be shy to do all you can to minimise risk and maximise chance of success.
What this means is acquiring & effectively spending wealth for extended lifespan because purchasable items CAN help you stay alive longer.
Before battle: do all you can, get the best gear etc. (see more below).
Outset of battle: if you are in control of the creation of an engagement, use that to your advantage too and create only the type of engagements where you have much greater chance of surviving. Do not risk 50-50% win chance engagements or even 60-40% ones (where you have the advantage). Instead try to get into 80-20% engagements.
Once in battle: do not sit out in the open against an archer exchanging shot for shot (use trees or shield for cover when it makes sense), initially try to approach from behind if possible, do not be shy to withdraw from battle where it makes sense and appears possible.
First, obtain and and wear best possible armour and protective clothing.* If you have not done so yet, read the wiki page on Clothing - it will help you a lot:
https://unrealworld.fi/wiki/index.php?title=Clothing* On that Clothing page, jump to the bottom of page and check out the last picture which shows Armour Coverage Statistics screen and while in game, the keyboard shortcut for that screen is: SHIFT + A. As per name, that screen shows how good your current clothing/armour is against different types of attack, and temperature. One might have a different goal (lighter build) but personally my goal is always to maximise armour stat against each attack type (and temperature). Highest coverage colour code is Dark Green. As a starting point I suggest you aim the same.
Second, having (eventually) obtained the best possible armour, do something harder: keep it consistently on.* A lot of stories go like "I had the best armour but took it off while cutting a tree/fishing/swimming and forgot to put it back on. Then a very bad person/bear/wolf attacked me when I was not ready."
* There are very bad persons/bears/wolves in the game. Keep your armour on. Keep your weapons close to you at all times, also.
* Once you have more experience and protection then you can consider selectively taking it off without risking too much (protection = being offshore or being surrounded by bodyguards in the form of hired villagers etc.).
Third, numbers is everything (a.k.a.: do not fight alone)* Many good suggestions posted already but one thing I have not seen mentioned is dogs. While the name is "Unreal" world, it is actually pretty realistic in the sense that 4 bandits can beat you (single-guy) up and take your stuff or kill you if you resist and dare make their robbery difficult.
* Alternatively, when you are travelling with 6 to 10 dogs, you can beat/kill them up instead and take their stuff.
Having experienced both sides of the spectrum, I prefer and strongly recommend the latter. Be the surrounder, not the surrounded which mostly equates to being the victor and not the victim.
Note that with bandits you can actually decide to give up your wealth and save your skin however you may not have that option with randomly encountered wolves or wolf packs/bears/Njerps etc. so do not assume you can always avoid fighting for your life. Sometimes you are forced to fight to the death. For that reason, try to be strong and stay strong.
Just to be clear strong does not always mean well armoured & well skilled.
Regardless of how armoured you are, eventually your armour will be penetrated.
Regardless of how skilful you are with weapons (even if 100% with all weapons/shield etc.) numbers conquer skill so 1 njerp fighter + 1 njerp woman + 2 njerp kids will kill your 100% skilled, 100% armoured Terminator-like character (I guess it would then be called Terminated).
Purchased dogs can be your own mini army to counter-balance enemy numbers. They can act both as additional targets for enemies to be distracted with, and they could ideally kill the enemies for you.
Here is a visual example. In this picture one player character has bright coloured clothing and the other has a bright future:
These are the 3 tips I could think of right now. Keep sharing your progress and let us know how you get on; share the good & bad news, perhaps someone here can help further.
