# Islands & Boosters **NFT Isles** is something Walken has never seen before. These aren’t just any ancient patches of land surrounded by water; they’re your team’s *launching pad to glory* and ***venue for Isle Clashes***. To participate in clashes, a team of 5 CAThletes needs one island. > *Like all other NFTs in Walken, islands are available on the Marketplace.* Islands come in ***five rarities*** — but with a twist. The **rarity of an island** defines the ***island energy*** — that’s basically the max capacity for the number of Isle Clashes it can be used for before requiring energy refill. These **energy pools** are the same as for CAThletes of corresponding rarities: * *Common — 3 energies* * *Uncommon — 4 energies* * *Rare — 6 energies* * *Epic — 8 energies* * *Legendary — 12 energies* The **cool-down time per energy** unit is also the same as for CAThletes: * *Common — 2 hours* * *Uncommon — 1h 45min* * *Rare — 1h 30min* * *Epic — 1h 15min* * *Legendary — 1 hour.* ## Booster & Debuff Every island is composed of **4 genes**, and the max rarity of these genes ***defines its overall rarity***. The 4 genes are *building, tree, scenery, and land*. But genes are not just about fabulous looks or overall rarity of the island; two of them determine **island’s booster & debuff potential**. Let’s break it down.

### **Tree Booster** As the name has it, the **tree gene** is responsible for the **booster** that you can use in Isle Clash. It works pretty much in the same way that the energy drink in Duels, but with an important difference. **I*****t boosts ONLY the most effective stat*** for a particular competition (e.g. speed for sprint), and the extra stat percentage depends on the rarity of the tree gene: *the rarer the gene, the greater the* boost. **Here are boost percentages by Tree gene rarity:**
### **Building debuff** Likewise, the **building debuff** depends on the building gene and works just like the laser pen in Duels — by reducing the rival’s stat by a certain percent. The range of possible percentages also depends on the gene rarity:
> *Summing up, the potential and value of an island are defined by **not only its rarity**. The* **rarity of specific genes** *— tree and building — play an important role in the team's clash performance due to the booster and debuff. This way we're adding an extra layer of fun and strategising to the game.* For instance, a legendary island may not be as cool as a rare one because of the tree and building rarities. Moreover, islands of the same rarity may be totally different in terms of booster and debuffs because of their gene set-ups. Each island, regardless of its rarity or gene set-up, has **10 booster and 10 debuff charges**. Once all the charges are used up, you’ll need to ***recharge them, for 100 Mysberries each*** (full recharge of the booster or debuff, not per charge). The number of booster and debuff charges as well as the cost of recharging them is the *same for any island rarity* — 10 charges. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
