Sanctara Shadow Realms — Idle RPG & Survivor Arena
Sanctara Shadow Realms is a 2.5D idle / auto-battler fantasy RPG combined with a live "Survivor Arena" co-op survival mode.
How the game works
Choose one of 11 heroes — six free classes (Warrior, Ranger, Mage, Priest, Rogue, Knight) and five special heroes (Serpent King, Kraken, Karadam, Phoenix, Reaper, which gain 2× EXP). Your hero auto-farms monsters on the map; you steer movement, fire skills and use HP/MP potions.
Leveling & how to grind
EXP required per level scales with your current zone. The grind curve is intentionally hard: levels 1–20 take about 1 day each, 20–40 about 2 days, 40–60 about 4 days, and 60+ about 6 days per level. Every level raises your max HP, attack and defense.
Zones & bosses
Six fantasy zones unlock by level: Forest Farm (1–6), Dark Dungeon (6–11), Desert Ruins (11–16), Ice Cave (16–21), Lava Arena and Ancient Abyss. Each zone has normal monsters, tougher "special" monsters (~3× HP), a boss every 25 kills, and a one-time Zone Guardian that grants a first-clear reward.
Loot & gear
Equip Swords (attack), Armor (defense), Rings and Belts (max HP) in five rarities: common, rare, epic, legendary and unique. Completing matched gear sets grants bonus stats. Sell junk loot for in-game Market Coins.
Survivor Arena
Join co-op survival rooms and endure escalating hazards — the shifting Red Zone, Blood Fog, Mana Storm, Monster Invasions and Boss Sieges. Outlast everyone else and climb the daily and weekly leaderboards.
