O.o
Wow. That... was SO specific... I want to argue but don't have any suggestions even remotely that detailed.
Here's my story: I'm the guy who suggested
Floris Expanded Mod Pack for a HA in no small part because it's just about all I play any more. I started on the
huge HA thread he was talking about suggesting what really was a failed proposition but since starting my own HA monster I have been converted almost entirely.
Here's how you do it:
1) Get the above-mentioned mod pack. It is everything and more that Native should have been. Additionally, it includes some options that you DO NOT have to use but can be very, very useful, especially for new players. If you choose to use the banking system to its fullest after day 100 you will not have to worry about money every again. If you choose to disable companion complaints you can take every single companion available for party members and make them responsible for all party skills so you can concentrate on being a BAMF HA. If you choose to use a little glitch I found you don't have to worry about running out of food. These three features (two of which are already fixed in the next version of the mod pack that is due this month or next) allow a player to concentrate on the combat in the game instead of missing out on great big fun battles because they are scared to lose their forces or because they are running out of food and allow the player to build a war machine character who's party is still effective. Oh, also, Floris as some REALLY good tier 7 horse archers, the very best thing to use in concert with a HA character.
2) select hunter, steppe child, poacher, revenge. If you look at the information
here you will see that maximizes archery skill as well as a doing something for AGI and STR.
3) Possibly before step 2, say yes to having all companions appear in the first tavern. Pick up Jeremus, Marnid, Ymira, Firentis, and Deshavi for free, and Borcha for 300.
4) You will be using every single companion but not all will have party skills that you care about. Upgrade intelligence in Jeremus and Borcha primarily and only up their STR and AGI when you need to up their ability to ride and wear heavy armor. Upgrade Firentis' AGI primarily and when you eventually get him Floris' CHA (he is an extra companion they added. Hireable for 20K but worth it.). Jeremus will be responsible for wound treatment, surgery, first aid, and engineering. Borcha will be responsible for spotting, pathfinding, tracking, and tactics. All 8 of those skills are INT-based and a character gets 2 skill points every time INT is raised giving 6 skill points every 3 INT increases and therefore every time a Skill is eligible to be increased. Since our two smarty-pants have only 4 INT skills they are responsible for that leaves 2 points available to increase riding and weapon master up to 3 and 4 or 5 respecively. Throwing in some PS once in a while doesn't hurt and I like to get their STR to 10 so they can get some good armor. Firentis also needs to get to 10 STR for good armor and then is responsible for Looting and Foraging (an added skill that allows you to augment you food supply). Floris will already be past 10 STR so you don't need to worry about that and given his high level is tough to improve upon but he has 6 Trade skill when you get him and lots of CHA, making him perhaps the best candidate for being the party trader. However, he also has 6 persuasion making him your best diplomat if you start your own kingdom. Katrin is the second choice for party trader because of her naturally high CHA and since she is much easier to level than Floris might infact be a better choice, I don't know. I just thought of it and haven't looked into it. Everyone else gets INT to 15, Trainer to 5, then every other upgrade is to AGI and STR to make them better warriors. Turning off companion complaints in the mod options (camp menu) allows a player to take an utilize them all but they are still sensitive to raiding villages and caravans and whatnot. But it's okay. If you threaten to hang them they won't every actually leave.
5) Take your INT to 15 right away and get your training to 5. This is a personal suggestion and can be ignored just like taking the companions' INT to 15 and training to 5. This does two things for you: Floris Mod has xp and proficiency bonuses for higher INT so leveling INT first makes levels thereafter easier to get. The other thing is with 14 characters (yourself and everyone not responsible for a party skill) at high levels with 5 trainer you will find that you are training recruits up to tier 4 in 4-6 days. After leveling up your INT go hog wild on STR (for PS, IF, and PD) and AGI (for WM and riding). You will soon find yourself with a huge amount of HP (I got couch-lanced at low speed for 70 damage, killed the lancer and moved on with my day) and a hefty ability to draw a bow and strike with power. I noticed that guys with shields were a problem for a HA so got a 125 long, 44dmg, 96 speed, 2h mace that crushes through blocks and I love it dearly. I take a bow that is a nice mix of speed and damage (strong war bow) and two large bags of +3 dmg arrows with that mace and I simply cannot be taken in combat. I could do with more STR for PD but I'll get there soon enough.
6) Buy heavy armor for everyone and armored horses (I'm using horses with 40 armor and 42 speed instead of the slower ones available with 57 and am convinced the armor is essential. A courser might not get hit much but when it does, man does it take a lot of damage and in Floris you have the option of that damage slowing horses down or not. I prefer for it to so I can shoot faster pursuing horses and make them not faster any more.). I outfit my companions with 1h, shield, light xbow (can be shot from horseback) and large bags of steel bolts because I like to use them as a shield wall in front of my shield wall and as hand-to-hand (melee) heavy cavalry. I want them tough and hard to kill so I can use them to soak up losses that might ordinarily be landed upon my mortal troops. 17 heavy cav is a force not to be ignored and often clogs up the enemy enough that by the time the enemy gets clear my HAs are all over the place and impossible to catch, dangerous to pursue. My choice of xbows over regular bows was a choice to save on PD and pump my companions up on PS, IF, Training, Shield, and other skills. I chose simplicity and stoic defense over DPS.
7) In large battles I ride in first with my horde following me. I get the attention of the lead elements of the enemy as I angle to the right and then tell my men to charge as the enemy turns to follow me while I ride right past them. That puts a wall of my troops right into the side of the enemy cavalry and a wall of teal text on my screen. From that point on the enemy is at a severe disadvantage since I have killed or at least severely damaged their cavarly and therefore their overall mobility. After that my melee cav do their thing, keeping the enemy occupied while I and my HAs circle and pump shafts into the enemy's backs. In the rare cases where my whole force bites the dust they have already extracted MASSIVE casualties from the enemy and it takes a solid 100 cavalry or powerful archers to do me in. By the time it gets down to just me the chances of the enemy having enough strong troops to stop me is almost none. So you understand, Native HAs suck, Floris HAs rock like they're supposed to.
8 ) All that being said, you don't really need a large party. If you have high training skill in your party and are a BAMF personally you can get a lot of good troops pretty easily and then it's all good. If you want to have your own kingdom you might need more CHA for persuasion but IDK, I'm a loyal Khergit vassal (soon to be marshall I think and hope!) so I just keep my head down and perpetrate mass murder.
9) Go look at that other massive HA thread and skim through to see some of my screenshots. They tell a pretty sweet story about being a HA.
