Server reopened
April 5th, 2025!


About the server:

Serenity CO is a classic (Patch 5165)
"High Mob density, Low Drop rate, Medium EXP"
private server for the 2003 free-to-play MMORPG "Conquer Online" with several "Lore Friendly" custom mods, such as a Fastblade-like skill for Archers and Taoists, magic damage effecting Cure skills, and OP stuff like Toxic Fog and Talismans reworked.

Level 137 Max, Super 2 Socket Dmg -7, +12 Level 130 gear max.

What Serenity doesn't have:

This server attempts to keep the features the majority of players enjoy and ditch the ones people dislike.
There's no "Battle Power" used in damage calculations. No Lotto for CP. No Item Lock. No slot machines. No Horses.
The client is update 5165, which was just after Ninja was added, so there are no Pirates or any of the newer stuff.
The goal with Serenity is to get as close as possible to what the developers originally intended before it was turned into a cash cow.


The goal of the server:

Serenity was originally opened in 2012, and has been shut down and reopened many times over the years.
The primary objective with the 2025 reopening is to keep it running for the forseeable future to preserve it as it was more than to try to update and add or change a bunch of stuff.
I really like how Guild Wars 1 is just still going and the way it was all these years later, so that's really the model I'm going for here.

Rates:

The gold rates are set up low to hopefully help control hyperinflation by having a small gold supply and high gold value.

Drop Rates are ~5-10x retail drop rates, and are intended to feel fast but not so fast that items have no value. It would be nice to see people using the market. EXP rates are ~20x retail.

Monster Killing Race. Three tiers: Tier 1 - People with AoE (Scatter/EliteScatter/Pervade/FireCircle) + Cyclone. Tier 2 - People with AoE but no Cyclone. Tier 1 - No AoE. The system picks a random number of monsters at the goal for each tier. First to kill that amount of any monsters in their Tier wins.

Number Guessing Game. The system picks a number from 1-100, first to guess the number wins. An incorrect guess tells you how hot or cold you are.
