Right-click sets a ground destination; holding updates it every 50 ms. Movement begins at full speed, turns immediately, and stops at the destination. S cancels movement. A fixed 120 Hz simulation uses swept collision checks. The arena has no terrain, units, or network latency. Attack & dodge simulates ranged attack windups and cancellation in its own mode. View scale changes apparent size without changing world speed.

Movement speed is world units per second. The default 395 speed and 58 collision radius are tunable training presets, not a champion-specific certification. Spell shapes, timings, ranges, Flash (400 units / 15-second training cooldown), and the top-down camera are approximations, not patch-exact replicas. Random bursts launch two or three casts together after a shared windup. The cast origin locks its aim when the warning appears. Direction guides are an optional training aid. Survival uses a 50% burst chance and locks gameplay settings and disables direction guides; Flash and walking-only records are separate. Before adding a wave, the trainer checks sampled movement routes against existing and proposed hazards and rerolls or skips the wave if none pass. This is a bounded route check, not a proof that every possible situation is escapable. Replays show the two seconds before the latest hit. Retry restores the latest wave snapshot with its exact geometry and lets you practice it for eight seconds without new waves.
