The nostalgia of classic Ragnarok, rebuilt for the browser.
Same PRE-RENEWAL foundation you remember — EXP, job levels, drop rates, ASPD, HIT/FLEE, MVP hunts, WoE and card drops rolled from their official tables — now with a clearer interface, a modern client and more maps, castles and content than the original release.
The realm's current rates
Every multiplier below is read live from the game server configuration. Base and job EXP run at ×5 during the week and ×7 on weekends (UTC). Drops, cards and rewards keep their own multipliers, so the official 1/10,000 tables stay meaningful.

Level 285. Official tables. Every class at its own cap.
The realm runs the official level system on top of the classic base: every profession respects the cap it has in the official game, the experience tables come from the official groups, and the first 99 levels keep the Pre-Renewal values you remember. The kRO 285Lv expansion (August 2026) raises the fourth classes to base 285 / job 65.
Stat points per level
OFFICIAL TABLE · LEVELS 1–285The bars show what each level grants: 48 points at creation, the classic Pre-Renewal grants rising to 22 at base 99, the official Renewal curve up to 35 at base 200, and the violet stretch from base 201 — the talent points (0 in total by base 285, cap 120 each). Totals: 4,099 stat points + 0 talents. Stat cost keeps the Pre-Renewal formula below 100 (2 + (stat − 1) / 10) and the official one above it: 16 + 4 × ((stat − 100) / 5).
Base 285 · Job 99
EPISODE CEILINGThe administration panel raises the realm to 285 base and 99 job levels, but every character still respects its own official cap: Novice 99/10, classic professions 99/50, transcendent 99/70, third professions 200/70, fourth professions 285/65, Summoner 200/60 and Super Novice 99/99.
Official EXP tables
PER CLASS GROUPBase experience follows the official groups 99 · 200 · 285 and job experience the groups 10 · 50 · 60 · 65 · 70 · 99. Levels 1–99 keep the realm's original Pre-Renewal values; from 100 the official curve takes over.
Talents
POW · STA · WIS · SPL · CON · CRTFrom base 201 every level grants talent points: 0 in total by base 285, with a cap of 120 per talent. They are spent in the character panel and apply the official effects — POW weight and attack, CON hit and flee, SPL magic attack, STA and WIS defence, CRT critical.
HP & SP
CLASSIC FORMULAS- Maximum HPlevel × 12 + VIT × 8
- Maximum SPlevel × 2 + INT × 5
The classic formulas scale to any level, so nothing had to be replaced to reach the new caps.

Open the dungeon atlasClassic refining to +10. Official kRO tables to +20.
Up to +10 every rate, ore and fee is the Pre-Renewal refine table you remember. Past +10 the official Renewal table takes over: Carnium and Bradium, HD ores that downgrade instead of breaking, and Blacksmith's Blessing to keep an item safe from a failed attempt.
Refine aura
YOUR WEAPON SHOWS ITS REFINE
From +4 the equipped weapon starts to glow with the colour of its element; the halo grows with every refine, lightning and rays appear from +7, and the effect peaks at +20. Neutral weapons go from refine blue through violet to red. It is a Zethrone visual: the official clients only ship the anvil success and failure effects.
Safe limits
100% UP TORefining within the safe limit never fails. Past it, a normal ore can break the item.

Classic mechanics. Renewal world. Beyond the original.
Nostalgia is the base: the rules of the classic game, the interface of the modern clients, and more content than the original release.
Classic core
EXP and job curves, STR/AGI/VIT/INT/DEX/LUK, HIT/FLEE, critical, ASPD, refine and the zeny economy follow the PRE-RENEWAL books. Monster cards roll from their official 1/10,000 tables with the realm's card multiplier, and no autoplay, stamina or paid shortcut replaces the adventure.
Modern interface
Every map, sprite, effect and UI element comes from the official Renewal clients, merged by priority euRO Prime → resources → iRO → kRO: 2,327 effects, 896 costume layers, day and night, weather and a readable HUD.
More content
Four Novice Guild Castles — Fire, Earth, Air and Water — join the 20 FE and 10 SE strongholds, with 569 later-expansion zones catalogued. Nostalgia with more world, not less.
34 castles, one weekend schedule
Twenty FE strongholds, ten SE fortresses and the four Novice Guild Castles share one rotation, one global WoE clock and one persistent ownership system — Emperium, guardian posts, GvG rules and daily treasure.
Every Saturday and Sunday · 15:00–17:00 UTC · 17 castles per day · the full rotation of 34 is assigned exactly once each weekend. FE strongholds raise 160 official guardian posts and daily treasure; SE fortresses open 4–24 chests and rebuild their gates stone by stone.
An atlas beyond the original release
From your first steps in Prontera to the latest expansion zones, every area runs on the same authoritative server engine — GAT collision, spawns, drops and minimap included.

Earn Zethrone Coin Tokens by playing.
The auction house accepts Zeny and ZCT, the realm's Play-to-Earn currency. Sell rare cards, gear and materials, pay a transparent commission on each sale and cash your balance out through the website. The server escrows every item and bid, extends closing auctions when a late bid arrives and reviews every withdrawal by hand.
ZCT earnings
Every sale credits the seller's token balance minus the configured commission. The full movement is written to an append-only ledger.
Anti-exploit by design
Escrow, anti-snipe, no self-trading, price floors and caps, withdrawal limits and manual payouts. No external API decides value or ownership.
No pay-to-win
The shop sells cosmetics and disclosed temporary help only. Combat power always comes from the world.
Temporary help. Permanent progress through play.
Starter Packs offer disclosed early-game equipment and convenience for a fixed period. No permanent item is sold: lasting strength, endgame equipment and competitive achievements come only from play. Optional support keeps the realm running.
Pay to Skin. Start with help. Play to Win.
Zethrone is funded by optional support: cosmetics and clearly disclosed temporary starter help. Nothing permanent or exclusive is sold — every item, stat and reward delivered through support can also be obtained by playing.
Zethrone Coin Token rules
Tokens exist so that time invested in the realm can become real money. The game server, not the website, executes every rule: escrow of items and bids, anti-snipe extensions, no self-trading, admin price floors and caps, withdrawal minimums and manual payouts. Every token movement is written to an append-only ledger.
