I have some awesome tips for you guys...
Tip1: Sparta kick mercenaries when they're on their last strand of health to knock them out and get the option to recruit them - they're always either a legendary or epic member.
Tip2: whenever you see a blacksmith, check what he sells, sometimes you could buy ancient tablets or cultist clues from him.
Tip3:If you find yourself constantly short on wood resources, break ships in half by ramming them. You get a lot more wood this way than you do by boarding them.
I was not good in assassin's creed but I improved my gaming skills by following gaming website like polygon, sportskeeda, xfire and many more. Guys don't give up always keep learning new things.
