Here is some basic knowledge about braveheart, it's very suited for the newbie, you can not miss it.
BraveHearts:
Grants 120 STA per 1 braveheart that is used. If it's up to 120 STA, it will not recover it anymore.
Obtaining Bravehearts:
They cost 2,000 gems from the gem shop, and can be bought with
real-world currency as part of various packs in the store. They can also
be purchased by attempting a stage when the player has insufficient
stamina, at which point the game will prompt the player to use/buy a
braveheart. Brave hearts can also be randomly won from chests when
opening gifts in your guilds gifts.
Bravehearts usage with VIP:
A player is limited in their usage of bravehearts, both by the number of bravehearts they possess/purchase and their VIP level:
| VIP lvl | Number of Bravehearts |
| 1 | may use one bravehearts per day |
| 2 | may use two bravehearts per day |
| 3 | may use three bravehearts per day |
| 4 | may use four bravehearts per day |
| 5 | may use five bravehearts per day |
| … | … |
| 13 | may use thirteen bravehearts per day |
| 14 | may use unlimited bravehearts per day |
The game can cause confusion to new players, when in their turf, they
tap on their stamina and it shows (for example): 'braveharts used: 0/2' –
this can cause new player to mistakenly believe they have 6
bravehearts, when they are simply VIP 2, and can use a maximum of 2
should they purchase them.
