Chaos Rift
An instanced PvE/PvP system with dynamic difficulty and epic rewards.

Overview
A flagship instanced event for a Classic server: a rift that opens on a schedule and scales to the party that enters it.
The challenge
The server wanted a signature piece of content that worked for both small groups and organized clans, without splitting the reward economy or becoming a lag source.
Our solution
We built an instance engine with dynamic difficulty scaling, wave and boss phases, optional PvP layers and a reward system tied to a custom currency with sinks. Instances are pooled and cleaned up deterministically.
Key features
- Scheduled openings with server-wide announcements
- Difficulty scaling by party size and gear
- Multi-phase encounters with mechanics
- Optional PvP modifiers for higher rewards
- Custom currency with economy sinks
- Deterministic instance lifecycle
