Guide:The Torch God strategies

Summoning
The Torch God is summoned when the player places around 100 of any type of torch anywhere below the surface at 200 blocks deep.

Terrain Preparation

 * Open areas are useful as you have a lot of space to move around.
 * Different torches have different flame colors. Crimson Torches are a bad idea to use, as the flames are almost impossible to see. Using Ultrabright Torches will give you an easy time to spot as they have very bright flames.
 * Creating a loop of Minecart Track around the torches can be an effective way to dodge the fireballs easily.
 * Circling the flames using Rope and Platforms is an easy way to avoid being hit.

Armor

 * An Ultrabright Helmet can be used for greatly increased vision at the cost of a possible higher defense helmet.

Accessories

 * Items like the Black Belt and Cross Necklace will completely stop damage altogether with dodges and immunity frames.

Potions

 * Using Calming Potions will stop the extra enemies from spawning, allowing you to focus more on dodging.
 * Vision-increasing potions like the Night Owl Potion makes the projectiles easier to spot.
 * The Ironskin Potion will help you tank in case that you got hit by a flame.

Tips

 * Enabling autopause will be helpful to dodge the fireballs easily by planning your next move every time you open your inventory.
 * Using Peace Candles will stop the extra enemies from spawning, allowing you to focus more on dodging.

Alternative strategies

 * The projectiles can be easily avoided by placing all the torches in the center of your arena, building a large open space underground and moving in one direction (near the edges) during the event.
 * Good additions to your arena are a rope ladder, as dodging the flames vertically is easy. Non-torch light sources, like lanterns and campfires, will help you to see better.
