Edit- 11/20/22: A bit late in kinda updating this, sorry folks. Few patches ago we received another beneficial patch where potions have been implemented into your hoard level. You get a potion every 25 levels. At level 200 you receive your first power potion and every 25 levels after you will receive another one. So with tons of gold and hoard treasures any faction will become significantly easier overtime instead of having to wait for an event to roll around and going for that faction then. I’ll try to condense and update this whole guide at one point to make it flow better. But for now, most of you guys know the drill on how to work this. Keep at it. :D
Edit-9/18/18: Faction events are super beneficial to your success on getting maxed renowned. For anyone who didnt know or didn’t realize, the faction events always start that faction at lvl 20. However you keep all the stats you put into the horde regardless. Meaning if you made it to 200 and your horde stats gave you plus 20 to everything, during the event you will keep that bonus and get to start at the bottom once more. Which results into tons of easy farmed chaos shards, gold, souls and glory(though the gold and shards are what really matter here). For those who don’t know where to find this, it’s under the game tab where you find the daily dungeon, forge, ect. It also works just like invasion and raids; you can use your gems to acquire that factions troops more delve tokens and treasure to help lvl up the horde lvl.
Edit-12-9-19: Marky mentioned that upgrading the kingdoms past 12 is a great idea as it increase horde levels by 25%. That’s huge depending on your level for the faction
*** Spoiler - click to reveal ***This is more of a template solution on how to work you way towards getting this achievement. From what it appears, to reach max renown you need 2500 for whichever faction you choose to play with. You get renown from 4 different ways that tie into the delve mechanic of the games. The 4 options are,
Highest level delved - 1,000 points
Highest level delved with faction units -500
Horde level -500 points
Highest level delved without casualties -500 points
Each one has a max amount of points you can contribute to each. I’ll be posting that number next with the names I showed above. The horde level should be your first and easy to max to help you work towards 2500 renown. For those that don’t know, you can earn treasure from the chest you get for completing your daily delves. You then would trade them in to the horde vault to gain levels for bonuses to be used in your upcoming delve battles(bonus attack, health, armor and magic for all troops).
Each faction you can only use the two colors that are associated with the faction.
All Seeing Eye - blue and green mana troops
Hall of Guardians - brown and yellow
Crypt Keepers - purple and red
It doesn’t matter which one you choose. But I would recommend the one you have mythic troops that are trained and you can work with. Things to note. You cannot change the order of your team once you start the delve. Also if an enemy troop switches your troop order or transforms your troop into something else, it’s permanent. Meaning if your fire bomb(example troop) was turned into a toad, the next battle it will stay a toad. So be very careful how you approach certain battles knowing this ahead of time.
*Good ol MemoriesofFinal have a good tip some of you may want to see to help decide which faction to use. With him unlocking the achievement he has ordered the factions in which would be easiest to hardest to work on this achievement for. So thank you for the heads up
Crypt Keepers
All Seeing Eye
Hall of Guardians-(faction troops are fucking brutal).
For the time being, I’m not sure how it factors how many points you get based on the current level of the delve for the 3 that relate to delving to increase your renown. Based off of how much you can benefit from the horde level boosts, it might be wise to not go as far as you can right away and balance between your level delve increase and staying at certain points until you get a decent boost to work on all three options.
If anyone has recommend teams or any other useful tips, feel free to mention it and I’ll update this as we learn more about this and the better tactics for this. Also incase anyone doesn’t know, you get chaos fragments for completing delves and opening up chests. You then use those shards in the portal tab to acquire either troops from that faction or treasure. Good luck everyone. This will take a bit of time to achieve.
Update: I found some numbers about the progression for 3 of the requirements.
Horde: for every level you gain with it, you get 5 renown.
Best delve: For every time you clear a level for the first time you get 20 renown. So since I complete level 50, I have 100 points.
Best delve/no deaths: Every level you complete you’ll get 10 points. So I managed to level 50 with no deaths and I’m currently at 50 points.
Faction Delve: have no input yet as I don’t have a 4th member of the faction to give it a shot.
Edit #2: From there forums it appears we get a new faction every 4-5 weeks. If that's the case we may end up with a better option for duo color teams and more rooms to get better rewards. I'll edit this edit once I learn more or when that actual new faction arrives and if I can pinpoint how long for each upcoming one to be released.
