Mechanics guide
This sim trains the movement and positioning of the Zulrah boss fight in Old School RuneScape, cycling through its color-coded forms.
- Serpentine form (green): Zulrah attacks with ranged projectiles. Keep moving so the shots miss.
- Magma form (red): Zulrah stares at your current position for a moment, then tail-whips that exact spot and stuns anything still there. Move away as soon as the stare locks.
- Tanzanite form (blue): faster magic volleys, sometimes in a spread of three. Dodge the bursts and watch for the angled shots.
- Venom clouds: toxic pools linger on the ground. Standing in one burns you, so path around them.
- Snakelings: small minions chase you for a while. Kite them and do not let them touch you.
- Jad phase: the finale alternates fast ranged and magic volleys. Stay sharp and keep dodging to finish the kill.
