Everything you need to know about OnceWorld
OnceWorld is a simple and casual 2D solo-play RPG. It reimagines classic MMOs from the mid-2000s for mobile, featuring easy controls and deep progression elements like leveling, pet raising, and arena battles.
In OnceWorld, character progression involves leveling up your hero, distributing points into seven basic stats, and reincarnating at the level cap to increase your overall level cap and available stat points.
Yes, OnceWorld allows players to capture monsters using special materials, turning them into pets. Pets grow stronger by fighting alongside you, and some learn skills. You can also feed them materials to raise their stats.
OnceWorld characters distribute earned points into seven basic stats: VIT, SPD, ATK, INT, DEF, M.DEF, and LUK as they level up. Resetting stat distribution requires a special in-game item.
OnceWorld equipment enhancement uses materials from adventures. Each attempt has a success rate; materials are consumed on failure, but the item itself never breaks. Specific items can increase the success rate.
Accessories in OnceWorld are items that grant special effects when equipped. They level up by defeating enemies while worn, which enhances their effects over time as you progress in the game.
The Abyss Corridor in OnceWorld is a ranked mode accessible a limited number of times daily. Players clear floors by defeating all monsters as fast as possible to achieve higher rankings and earn treasure chest rewards.
The Kin-Slayer Rite in OnceWorld is a pet ceremony that resets a target pet's kin-bond, level, and accumulated experience to zero. This process enhances the pet's base stats but causes slower experience gain thereafter.
Yes, you can view information about captured monsters in OnceWorld through the Monster Encyclopedia. This section displays their stats, and any monsters you have captured are clearly marked.
The Arena in OnceWorld allows players to watch monster battles several times a day. Participants choose a favored team; if that team wins, players earn Arena Coins redeemable for valuable materials at the Arena Shop.
