Balance comes from KlasGame, the only dealer the site lists, and turns into KC in the store at 10 AB = 500 KC.

Where cash makes a difference, per the site

Going by the site's rates, cash matters most for high upgrades and crafts. A Blessed +7→+8 is 2%, or 4% with Trina; a Shadow Piece lifts the Ruler weapon from 3% to 6%, Dragon Armor from 10% to 20% and the Draki Pendant from 50% to 100%. No mob page lists a Shadow Piece drop, while the Trinas Piece has a free source in Atross.

For farm speed the gap is DC Premium: 26% drop and 100% coin bonus. In PK, War Premium adds +70 NP per kill. A player without premium can farm the same spots, just without those multipliers.

Rule: no buying GB or items for real money

The user agreement flatly bans trading GB, items, characters or KC for real money, and accounts caught doing it are banned indefinitely. So the only rule-safe way to spend cash is buying balance from the dealer and using the store; paying another player for items gets you banned.

FAQ

Can you get Trina without paying?
Yes: Trinas Piece is on Atross's base drop list. The site doesn't give the drop rate.
Do the forum events still hand out prizes?
The site has no new forum event posts after April 2025. The Introduce Your Clan and Introduce Yourself prizes belonged to the launch period.
What's a PK Paket and how do you get one?
It appears on the base drop list of Chef and Halloween Pumpkin. BianKO's site doesn't say what's inside.
Can you give a bought premium to someone else?
The site says nothing about it. The premium page only lists the bonuses and the 30-day duration.
