Hi everyone, a lot of players asked me questions, when i gave them tips how to level up all civs fast to level 40, so i figured out a way for at least mediocre players: 1. Create a empire with every civ and get the milestones, which are availible at the start like Slyrevick mentioned: "You don't have to reach lvl 40 to get milestones You have milestones at lvl 5,10,20 Talatat Construction being excellent to level up faster" Aryzel already made a list with all the milestones, there is mostly a clear decision which milestone to pick, some of them are dependend on your playstyle. Aryzel already gave tips with the colors "good choice" etc. https://forums.projectceleste.com/threads/guide-part-4-milestones-needs-input.4454/ Once you choose all the milestones on every civ you can pick one milestone from every other civ on the civ you are currently playing, which will give you instantly advantages for the faster leveling up. Just go to the "Milestones" and click on one milestone of another civ, it will have a white circle around the milestone you choosen. The milestone you choosen from another civ can be changed without cost. But keep in mind, the one you actually choosen from leveling up is permanent it is really costly to change (1000 empire points), so choose wisely from the start. 2. Start with a pro civ: Persians, Babylonian or Norse, so you will be able to do the questline: "Northern Hold". https://ageofempiresonline.fandom.com/wiki/Northern_Hold Play till the quest "City Defense: Sens". After this a guy on the fire pit gives you the global quest, where you can get the XP-Boost and the Coin Boost (Coin boost just comes in handy, when you want to get a few extra coin. You can actually do several 10k coin missions and don't get the reward. Use coin boost (works 24 h) on one civ and then get all loot "coin boosted" for every civ, it will work for 24h for all civs). You can do any city defense, but i think Sens will be the easiest. Just get one treasury at the start, get the victory tower nearby and sneak the enemy victory tower or at least hold 2 victory towers at your side. Leave a mycenian defender on the other treasuries, so the enemy does not get too much gold, so you can win the mission and get both boost for one quest. Sometimes it is easier if the hero sokes up some damage and get killed, he will be faster replaced, then he will completely healed. The best way to use XP boost is to do several missions without getting the loot at the first day. On the next day use XP boost and get every loot for all civs and missions you prepared, you will get +50% XP for all mission. Then you have 24h to level up. Make sure you use it on a saturday evening, so you can play the next day again using the same XP boost. 3. Use the level 20 questline: Fertile Crescent. The missions give massive XP with the XP boost and are imo really easy, once you figured out the optimal way: I usually use Infantry or other key units like babylonian Lancer + rams from siege work, often you don't need more then copper armory and Silver Age. https://ageofempiresonline.fandom.com/wiki/Fertile_Crescent_Quests I usually play until mission 25 without he amrosia project, which are funny missions but don't give so much XP. Now your civ is around level 30 and you can start with Athen's Questline (for advanced players). The 4 starting missions are a bit tricky with strat, but outside the event times you will usually found a coop player, which also want to complete the questline since you can get Mileto, Sardes etc. legendary missions. If you are good enough with coop you can even spear rush the AI on certain maps and snipe the other tc with good enough teamwork. The Cyprus Questline is much easier for beginners like FrogsPoison mentioned so maybe go for this Questline first! You will not even have to complete the Questline and you will be already at level 40, by also using the XP boost on the next day. 4. If you are fast enough you can even use the still active XP boost on a level 3 civ like romans, celts or greeks to level up faster till level 20, where you get the next XP boost and repreat the procedure. 5. There is a fast tactic with egyptian, where you get fast age 2 and use the champ spear upgrade, getting all the food at the map and you can finish most missions under 10 min with spamming mainly spears and couple of axeman. I saw that in pvp games, where TheMista used the champ spears to rush the enemy, i think it got nerfed in pvp, but in pve it still works. 6. Once you are level 20 you can go to Tarsos and buy: Mycenean heavy gloves for all units or this possibility: https://search.projectceleste.com/?tab=0&search=gloves and i also buy Hood of the Resolute in this store, it is very cheap, even when you will replace these items very late in your gear progression though. 7. Rare or even uncommon advisors help also, like Age 1: Irene (some civs get it right at the starting quests for free) Age 2: If you can effort: Dumnorix, Zeno (for harder quests) or free: Village Elder. On many easy quests it is not neccessary to set up a market trading route, since once it would kick in, the mission could be already over. Village Elder in Skirmish rush: https://forums.projectceleste.com/threads/skirmish-rush-guide-and-pre-40-bis-list.5340/ You can easy win the advisor with every civ if the opponent is standard babylonian (he will have shield bearers, which don't hurt much). I use oasis small map, very high player resources and just rush the TC with spears or Sparabaras. Age 3: If you can effort: Pamphilos or Seneb (only egyptian, he is cheap in GM) Age 4: King Agamemnon (free in Skirmish rush) 8. How do i get coins? The advantage of having all civs level 40 is, you have 7 coin boost and can play the 10k gold legendary mission. Learn the legendary missions via Youtube: https://www.youtube.com/c/RekiemOne is one i use but there are also other good pve players you can watch, just type the civ you use and the mission in youtube like: age of empires online celts valley of king solo (or coop). If you get the tricks from a person, who is able to solo, you will usually get the way to win in coop much easier. Also you can do event missions on all civs and get more event gear you actually need and you can sell a lot of stuff later for good prices. Once you are level 40 epic gear is mostly good enough to do the harder missions, beside the legendary advisors, you will need, but one day you will get them. Have fun!
