# Battle system

In Tribal Island, the battle pet NFT in the earlier version of the game and the character NFT added in the later version are responsible for the battle.

### • **Battle gameplay**

Pet NFT 3v3 PVE/PVP. Battle pets should defeat all opposing pets to win the game by performing “normal attacks” or “skill attacks” on the battlefield.

### • **Battle operations**

Each pet has a speed attribute, and whichever pet's speed value reaches 100 can launch an attack. Firstly, gamers have to choose to release a “normal attack” or a “skill attack.” After the selection, the gamer needs to choose the release target. When releasing a skill, the gamer has to choose the timing for skill release to achieve additional skill effects finally. A power bar represents the skill timing. In order to facilitate gamers to advance the level, all the operations are divided into “automatic operations” and “manual operations”.

### • **Power bar**

Three colors: white, red, green.

1\. White: normal damage

2\. Red: Damage reduced by 0.7 times

3\. Green: Skill damage increased by 1.2 times
