Boss-Forge is a Polish Open Tibia server running client version 15.00–15.11, based on the Summer Update content. It features a real Tibia map with over 200 bosses available for hunting, making it one of the more boss-content-focused servers in the OTS scene. The server is hosted in Poland and maintains a 99.98% uptime track record. It runs a Classic PvP world type.

Boss-Forge uses a modified progression system centered on boss farming rather than raw EXP grinding. Key rates include Proficiency XP at x2 from monsters and x5 from bosses, Wheel of Destiny Points at x1.5, Loyalty Points at x20 per day, Grizzly Adams Points at x5, Bestiary Kills at x3, and Bosstiary Kills with multipliers of x1 (N), x3 (A), and x6 (B). Imbuements are stronger than on the official servers, with enhanced mana, healing, critical damage, and resistances. Rare item drop chances from bosses are increased, and charm reset costs are reduced.

The server includes the Monk vocation introduced in the Summer Update, autoloot, autobless, auto gold deposit, offline training on dummies and trainers with no X-Log kick, a roulette system, and a task system. These quality-of-life features reduce downtime and keep the focus on active gameplay. The server is suited for players who enjoy systematic boss hunting and collection mechanics on a modern Tibia client.
