Fire Emblem Heroes is one of the more balanced free-to-play games and you don’t have to pay huge amounts of money to have some fun. Nevertheless it depends on your claims, if you want to become one of the best players you will need more resources than you could farm.
New players should think about rerolling
Many players of Fire Emblem Heroes keep deleting and then reinstalling their game until they pull a strong hero. This might be one of the most boring and annoying tips of them all but it is definitely worth your time. If you end up pulling one or two five-star rated characters it was definitely worth the effort. As it only depends on luck it can take some time until you end up pulling at least one of the rare characters that are also the most powerful ones available in the game.
Use high rated Characters
Try to battle only with four to five star rated units even if they aren’t your favorites . They will usually perform better in duels as the growth potential is bigger.
Collect daily Rewards
If you start Fire Emblem Heroes once a day and play a little bit you will get rewarded for it with different items. On weekends there are special prices available so make sure to collect them if you can.
All of you should have a look at the Fire Emblem Heroes tier list, there you can easily find out which units you should try to get. From time to time you should visit the tier list and look for changes as this can change with every update. As of now I would suggest you to get Lyn, Nowi, Reinhardt and Zelgius.
Upgrade your Castle
Most players tend to spend all their Orbs on hero summonings but they should rather focus on upgrading their Castle as this will give them a permanent experience boost. You can find the castle upgrade on the Home screen of Fire Emblem Heroes by pressing the green castle icon on the right top.
Get more Crystals and Shards
By tapping the fountain on the home screen you can find the quests menu. There you will be able to find story line quests but also monthly quests by pressing the right arrow next to crystals and shards. Monthly quests have special requirements like having a bow-user in your team or only use a certain color of units.
Watch your Stamina
Nintendo wants you to enjoy Fire Emblem Heroes in short doses so you should not spend all your stamina at once. Most of the tasks will require stamina so you may have to wait sometimes before you can continue plying the game.
Link your Nintendo Account
You can get 10 free Orbs for linking your Nintendo account to your Fire Emblem Heroes game. If you did that you can easily collect the resources by pressing the fountain and then tapping on the blue and silver icon at the right top of your display. The icon should be glowing if you did not collect the Orbs already.
