Tip and tricks

It is always good to know the tips and tricks. There are some before starting the mini-event that can save you gold.

• Activate your Guild bonus “CHEAP UPGRADES”. Depending on the level of your guild it can save you up to 20% gold. This can be found in the bonuses tab of your guild. Learn more about Guild Bonuses. 
• Each time you rank up, your Journey Keys get refreshed. It is also a good practice to use up all the keys before your next rank. This way you can get Ancient coins to spend in the Journey Shop.
• You may also consider to reborn your heroes to reset them to level 1. You may want to read up on more info about reborn before doing so.
• Start with the heroes that you use in your Squad. Then, with your low level heroes as they require less gold.
• Leveling up your skins and pets also count with this event.

Estimation of the number of available level-ups and the required amount of gold

It is not nice to end up in a situation, where you have done something like 45 upgrades for a 80 upgrades milestone, but have no resources left to actually finish it. That's why after completing each milestone it's a good idea to estimate how many upgrades you can still do. And a script exists to automate this process. Usage instructions:

• Open the "squad" view page in the game. Activate the filter, which shows only upgradable cards.
• Go through each rarity and prepare the list of your heroes. Each line should include three parts: rarity, the number of cards and the current hero level. For example, "r 356 5" means "rare hero with 356 cards and level 5".
• Open https://play.crystal-lang.org/#/r/6jr9/edit in your browser and edit the parameters for the plan_levelups function at the bottom, replacing the provided example with your actual data.
• Press "Compile & run code" button to receive the result.

Currently the following example

plan_levelups(
  guild_discount:     16,  # guild bonus for levelup cost decrease
  fable_discount:     18,  # optional fable bonus for levelup cost decrease
  number_of_levelups: 55,  # the number of desired level-ups
  upgradable_cards: "      # the list of upgradable cards: rarity quantity level

  c 2000 1                 # a 'common' hero with 2000 cards and level 1
  r 982 7                  # a 'rare' hero with 982 cards and level 7
  l 45 1                   # a 'legendary' hero with 45 cards and level 1
  e 155 6                  # an 'epic' hero with 155 cards and level 6
  
  r 356 5
  r 120 7
  r 639 11

")

produces the following output

Trying to plan for up to 55 level-ups (level-up cost discounts: 16%, 18%).
With your cards you can do level-ups in this order:

     common 2000/25 Lv1  ->     common 1975/50 Lv2  (34 gold)
