Switch between inventory and prayer book with 1 and 2 keyboard keys.
You can synchronize Hunllef Helper by starting it and then immediately refreshing the page to start new game.
Idle player is yellow. Attacking player is blue. Player during the casting tick (immobilized) is lighter blue.
Black floor is safe. Red floor shows where unsafe floor will appear in 3 ticks. Yellow floor is unsafe.
Red circles are tornadoes. They are very unsafe.
The setup uses two combat styles B(ow) and S(taff). Big letter on the player is their currently equipped weapon. Small letter on the top is prayer.
Hunllef is white and standing on it is unsafe (stomp doesn't delay the attacks). Prayer is in the middle, attack style on bottom, and total damage taken on top.
B(ow)/S(taff) in the inventory swaps the weapon. In the prayer book it swaps the prayer. F(ish) in inventory heals.
Game keeps track of your performance. Once your health reaches 0, your stats will freeze and turn red (can be disabled in options).
Once you start reaching 500-600 damage and 80/80 performance, you should be more than ready for the real CG fight.
Learning tips
Ignore attacks and prayers first. Only focus on running around and not getting hit by floor and tornadoes.
Once that's mastered, start switching prayers. Aim for surviving whole game with near 100% survival efficiency (you can disable score freezing on death in options to help track this)
Finally throw in attacks and weapon switches and start maximizing damage
