Excellent and Ancient

Excellent

An item with a glowing option — extra damage, life per hit, speed.

From the ground, it comes with one option 75% of the time and two 25% of the time. From the golden invasion box, it comes with two.

Chance by map

Where	Per kill	One every
Lorencia and most maps	0.010%	16 h
Lost Tower · Atlans · Tarkan · Icarus	0.020%	8 h
Kalima · Aida · Crywolf · Kanturu · Land of Trials	0.035%	5 h
Karutan · Raklion · Vulcanus · Swamp	0.050%	3 h 20

At 600 kills per hour. Farming Karutan pays five times Lorencia.

The box is faster than the ground

The shortest path to an excellent isn't farming: it's the golden invasion, which runs six times a day and produces about 8 excellents per day in each world.

The difference is that the ground is constant and the invasion is a window of a few minutes, contested — and where half the monsters give nothing.

Ancient

A set piece, with its own option and a blue glow.

Only drops in Land of Trials, at 0.15% per kill — about one an hour. Across the other 66 maps on the server, zero.

A single piece is worth little

The prize of ancient is the set: five specific pieces among 108 that can drop.

The roll ignores the monster's level and the map — any kill that hits the rate draws from all pieces. That's deliberate: without it, completing a set would be impossible.
