🏝️ GrandSeas
The ultimate acid ocean survival plugin for PaperMC! Build islands, manage teams, and dominate the toxic seas.
GrandSeas is a modern, feature-rich SkyBlock and AcidIsland alternative. It brings a completely fresh experience to island survival servers by replacing the void with a toxic, acidic ocean.
Players must expand their island, manage resources, form teams, and deposit valuable blocks into a centralized Point Storage system to rank up and upgrade their island.
✨ Features
- ☠️ Acidic Oceans: The water surrounding the islands is toxic! Players and mobs take damage when touching the water or being out in the acid rain (fully configurable).
- 📦 Point Storage System: Instead of placing valuable blocks manually around the island to gain levels, players can deposit blocks into a centralized Point Storage GUI.
- 📈 Dynamic Island Upgrades: Players can spend their Island Bank balance to upgrade their Island Border Size and Ore Generator rates.
- 👥 Advanced Team & Trust Management: Complete control over island access. Add members, promote leaders, or give specific players a
Trustedstatus to build without joining the team. - 💰 Island Economy: Built-in island bank system. Deposit, withdraw, and manage island funds directly through the GUI.
- 🛡️ Robust Protection: Extensive island protection preventing visitors from griefing, opening chests, or interacting with the environment.
- 🎨 Modern GUI Menus: Almost every feature is accessible through beautiful, interactive menus—no more remembering complex commands!
