Here are some tips for getting this badge legit.
- Set speedhack to 2x speed. This makes the game more bearable. Any higher and you won't be able to take any actions immediately after battle until the server "catches" up with you.
- Upgrade your hero count as soon as possible until you have a total of six. Then, focus on unit count and atk/def/vit in terms of upgrades.
- Focus on upgrading resource buildings before anything else. Then, focus on working towards tier 2 units. Your final army will consist of one stack of tier 2 infantry and five stacks of tier 2 archers.
- Spend your "free" coupons (for leveling up, etc) on Horns of Summoning at the shop and fill all your hero slots with blue or better heroes as soon as you can.
- Join an alliance as soon as possible and do the alliance daily missions every day. Save up your reward points for either level 40 equipment sets (3200 points for a full set) or for crafting level 40+ gear.
- When you hit level 40, do the daily bounty quests.
- Do the highest Hell dungeon you can handle three times a day. Use the resources to upgrade your buildings and research.
- When you're not active in-game, go to the highest level training coliseum (building with a bullseye icon) you have access to and train your char/troops. Re-train every 2 hours. (If you have VIP, you can train for 24 hours at a time)
- Try to complete as many storyline quests as possible. They usually give silver/resource rewards that will boost you up very fast, especially on the first two days. Do NOT waste your resource cards. At first, you'll feel like you have infinite resources. After a few days, you'll find buildings need 300k of every resource to upgrade. Upgrade wisely.
- You can try the final Hell dungeon at army (heroes) level 47. On the final battle (level 53 archmage with 9000 army strength), I recommend having at least one hero with a sh!t-ton of attack (I think I had about 900 or so -- just slap your best atk gear on your highest atk hero), and put him on the bottom right hand corner. He should be the last one to die, and will get the most hits in that fight. All your other heroes (with the exception of the tank, who should be loaded up on defense -- 700+) should have reasonable 600+ atk as well, so craft some weapons and necklaces for everyone, or have a couple of heroes with the level 40 alliance gear set. If you're still having trouble at 47, you can craft the level 50 weapon which will give your army a huge atk boost. Just make sure to check the crafting recipes so you don't sell the required ingredients. If you're doing all the daily quests though, you should have the "gear" ingredients. You'll just need to get lucky on drops or buy the other materials at the alliance shop.
I was able to get the badge in about a week. I logged in every 2 hours to retrain for about 10 hours a day, and played about 2 hours each day (dungeons and quests only). There's no need to grind. At all. Good luck.
