Had 1-3 growths at spawn, week 2 - double growth for all creatures :D so there were 59 archers,
and I didn't bother upgrading and just leveled, luckily I found Bless.
Went at a moderate pace, level 20 on day 20, but Light was only given on day 21 :), so I had to grind to level 23 before the split.
On day 4 I ran the route: adjacent zone - center - secondary zone, on day 5 I broke into the treasure zone, and on day 6 we met the opponent's GG there.
Even though our armies were evenly matched, Ossir was noticeably older than Ingvar, so it turned into a one-sided game.
Here's how I leveled:
Ossir lvl 30: 29-22-16-23
3 racials - Rain, Arrow
3 attack - Ballista, Archery, Tactics
3 logistics - Pathfinding, to Intelligence
3 defense
3 luck - to Elven Luck (thanks to TE, now it can be taken for Ossir too)
3 light - Protection + Fire Resistance, Blessings (tried for 2 days to have the mentor unlearn it in exchange for Mass Haste, but no luck, pushed Eternal Light 4 times)
Thanks to the opponent for the game!
