The same tactics as i said before(solo troop), but with better equipments found in Verona.
By the way, in this game i defeated Katahu at about 2 am day5, to get the last stone in Tekron need 14+5 hours so i can clear the game at day5 23:30, then i continued playing and got this score.
day7,
LV58,
0 losses,
everything seems perfect but..
How could i missed a task!!
Finally i got it , i killed this monster without having the contract at the early game>_<

that's really a unchangeble mistake.I can't play all again...
Now let's talk about game, there are 4 red dragons in Rusty Anchor Tavern so i need to reach 2000 leadership quickly, luckly there i can buy a head of +600 leadership so i won't learn lv3 golry(but lv2 is needed).
After that in Verona i found twilking boots, ancient amulet and the scale set(shiled in Verona other 2 in Debir)...how can i expect more XD
But everything is balanced, i can't find mana spring scroll even i am lv25!!!That made me learn +8 mana per round even before lv3 distortion magic...
At last i found the scoll on battle field, oh my god i missed spring too much....
So after that everything worked fine.
Here's my process of early game before i got the red dragon:
In Debir 1*4 inqusitors + Royal thron, pet dragon did half the damge(another half is fire arrow).
About the 4 heroes(3 task and 1 in casle), add royal snake to finish the battle quickly to keep 0 losses.
here i only got 750+ leadership(2 royal thron need 760..sign), so i have to learn lv2 glory.
In Scarlet island, cuz of lv2 glory, most of the enemies are not strong enough, even the have beholder and archmage..
i used 3 archmage(only can find 3),9+1 inqusitors, 17 royal snakes and 2 royal thron cleard all non-hero creeps, and got lv2 grand stratge medal.
I have enough leadership to defeat the guard of Rusty Anchor with 0 losses.(the taven had 4 royal griffins)
But i didn't done this only to save gold for the red dragon(need 40k gold total )
Then i had 1 red dragon and cleaned up Rusty Anchor except zagzag(cuz i didin't have the contract).
================================================== ========
My route
The first loop Debir--Scarlet---Rusty Anchor--Verona--Bolo---Debir
bring the lady back and get her task, also get the stone in Bolo.Becasue i have been to Verona no i have enough gold to buy all usefull items in Debir.
At this time i was at about lv20
The next route Debir--Verona-Montaro--Verona , finished all the task in the main land and reached about lv35.
Next, Dersu--Uzala--Elon--Nameless--Reha
and the final world loop Reha--Umakas--montoro--Verno--Montoro--Tekron--Rusty Anchor--Sclaet--Debir--Shaterra--Dersu--Elon--Nameless--Uzala--Verona
At last, i think there's still something to improve excpet the missing task.
In this game i only had 4 ancient knowledgy world scoll and no shark tooth but finally i still reached lv58,although this is the highest lv i have seen(in other's games),i believe that it's possible to reach lv59 with all exp bonus items since second time in Vernoa.
So the highest score may base on Day7+lv59. I hope someone can done this XD.
Day7+lv58 tooks me nealy 1 week about 36hours(real time) to play and killed too much of my mindcells ,
i should thank 1C company too much for this great game although i won't play KBAP oncemore, i think
