Easy Level Trick: Ian's Ballads supposedly require you to beat all the mooks before facing the boss.
While he is not the best, he is the easiest Legendary commander that can be maxed out relatively speaking and remains useful even after stronger Legendary Commanders have been released.
Disc-One Nuke: Minamoto no Yoshitsune is a Legendary Commander available to be purchased as soon from the start of the game and he easily surpasses all other Epic commanders that are given to you when you first play the game thanks to his bonus damage against Barbarians.
Arms Master Lohar in "Lohar's Training" event is treated as an "Elite Barbarian" which means he isn't treated as a Barbarian that Peacekeeping commanders deals bonus damage against.
Holy Site & Pass leaders and Ancient Ruin Barbarians often tend to be immune to all debuffs which meant governors couldn't just surround and debuff them until they can't fight back.
The number you get is fixed and they can't use Universal Scultpures to level up their skills.
Bribing Your Way to Victory: While the entire game can technically count as this, there are two commanders in the game (Minamoto no Yoshitsune and Hannibal Barca) that can only be obtained and maxed out by directly purchasing their sculptures.
Boring, but Practical: Tier 1 siege units don't proved as much troop power and obviously aren't as strong as the higher tier siege units but they provide the highest troops load for it's training cost and in the event your gatherers are attacked, you only need to expend a minuscule amount of resources to heal them not to mention that they recover incredibly quick.
However, they are only purchasable after the player has maxed out all the Gold Key commanders where by the time they're finally expertised, would very likely been power crept out of the meta and probably already maxed them out anyway given that they're infinitely more useful than them.
Bonus Feature Failure: Both Richard and Yi-Seong-Gye are available to be purchased in the Daily Special Offer where players can purchase the daily bundle for a random amount of said sculptures.
Battering Ram: They are available as the first tier of siege units.
The only scenario where his healing isn't harmful are during Ark of Osiris and open field battles where the former has unlimited space for hospitals while the latter don't have much space for Hospitals in the first place due to the maximum amount you can carry.
Even though Richard is a commander specialized at garrisons due to his skills, his healing ironically does more harm than good as having units healed while he is the garrison commander meant that your slightly wounded troops becomes severely wounded instead and in long drawn-out battles, this fills the hospital very quickly until you can hold no more space and your troops will die.
True they do have greater loads for gathering and plundering but if you got attacked while gathering with higher level siege equipments, you will be incurred with a huge amount of hospital costs, easily greater than whatever resource you will get while at level 1, the costs to heal them is minimal while also being healed at an incredibly quick rate. While they are able to deal greater amount of damage to watchtowers and garrisons, they are also equally weak to other unit types not to mention that there are no commander that specifically benefit them besides gatherers.
Siege troops beyond the first level count as this.
Additionally, commanders with the leadership talent has skills that enable them to amass even greater number of armies.
Higher levels means you can utilize greater number of troops.
Arbitrary Headcount Limit: How much troops you can run per commander is dependent on their level as well as your City Hall level.
Even if the threshold for Stage 3 of Past Glory is already reached, players can still donate sculptures so they can exchange the Hero Medallions in the shop, ensuring that players who slept through the event can still receive the rewards.
Any AP spent will be returned if the player has not engage in combat with the target.
If the alliance leader is inactive for 1 week, the alliance will automatically promote another leader based on activity and rank.
Eventually, once your kingdom has been stabilized, you will enter a new chapter in the Lost Kingdoms where your Kingdom will matched up against 7 other Kingdoms where you team with your fellow alliances to conquer the Great Ziggurat and prove that your Kingdom is the strongest in all of Lost Kingdoms.
