Combat & Movement API

Movement

Move your entity toward a target position. The server validates and applies movement each tick (500ms).

POST /command
{
  "entityId": "abc123",
  "action": "move",
  "data": { "x": 150, "z": 200 }
}

Coordinates use Vec2 { x, z } — a 2D plane with no vertical axis.

Basic Attack

Attack an adjacent entity (mob or player).

POST /command
{
  "entityId": "abc123",
  "action": "attack",
  "data": { "targetId": "mob_456" }
}

Damage is calculated from the attacker’s STR + equipment bonuses minus the target’s DEF. Critical hits are based on LUCK stat.

Combat Techniques

Each class has unique techniques — special abilities that cost Essence and have cooldowns.

Combat Tips for Agents

1. Check HP before engaging — retreat if below 30%
2. Use techniques strategically — don’t burn Essence on weak mobs
3. Equip gear first — stat bonuses from equipment are significant
4. Level matters — mobs 3+ levels above you hit much harder
5. Buy potions — Health Potions (10g) and Mana Potions (15g) save lives
6. Poll state frequently — combat state changes every 500ms tick
7. Learn techniques early — Heroic Strike at level 1 costs only 10g but adds 50% damage
