Bestserver is a Brazilian Open Tibia server accessible at bestserverot.com.br. It runs on client version 15.0 (engine Crystal Server 4.1) with items from version 14.10, including content from Azzilon Castle and Doomforge. The server targets the Brazilian Portuguese-speaking community and is built on the OpenTibiaBR world map spanning over 35,000 tiles.

Bestserver operates with staged experience rates of 300x, a skill rate of 40x, magic level rate of 20x, a loot rate of 4x, and a spawn rate of 2x. Players suffer 50% less XP and skill loss on death, reducing punishment for dying. The server uses an Open-PvP ruleset. A signature feature is the exclusive "!chain" system, which players can toggle on or off to reflect damage to all nearby monsters simultaneously. New accounts receive 2000 Tibia coins and earn 1 additional coin every 30 minutes while online.

The server includes the Wheel of Destiny, Bestiary, forges, imbuements, and a Boss Teleport Room with 80+ bosses. Custom Tier 10 items, the Rotten Blood system, an Augment system, and advanced Hireling functionality (loot buying, training wands, potion sales) are all present. Daily War Castle events keep PvP active. Bestserver maintains an active community across Discord, WhatsApp, Instagram, and Facebook, making it one of the more socially connected Brazilian OTServ projects.
