Enchanted Sword Shrine



Enchanted Sword Shrines are terrain features that generate as small caves below the surface. They can generate with a narrow shaft leading into the top of the cave. The cave's background is made of Flower Walls and features a small hill with pools of water on either side. Atop the hill rests a breakable background sword sprite. They generate in the surface or underground layers in dirt or stone terrain.

Multiple shrines may generate in a world, with larger worlds having a slight increased chance to generate more, although not guaranteed to generate any. They generate within 30% of the world edges with a 33% chance of generating a 1-tile-wide shaft leading up to the surface. The sprite has a 90% chance of dropping the Enchanted Sword and a 10% chance of dropping the Terragrim.

There will always be 1 shrine in small worlds, 3 shrines in medium worlds, and 4 shrines in large worlds. They generate within 30% of the map edges and always generate with a 1-tile-wide shaft leading up to the surface. The sprite has a 67% chance of being a fake sword and a 33% chance of being a real sword. Real sword sprites then have a 90% chance of dropping the Enchanted Sword and a 10% chance of dropping the Arkhalis.

Generation chance
The world will attempt to generate 1 to 2 shrines in small worlds, 1 to 3 shrines in medium worlds, and 2 to 4 shrines in large worlds, with each shrine having a 25% chance of being placed. The following tables represent the odds of having a certain amount of shrines generate in a world, depending on its size.

Tips

 * The shaft can be revealed by light particles that fall downwards through blocks. There are many weapons which spawn projectiles of this kind, for instance, the Dark Lance, Starfury, Jester's Arrow, Meteor Staff, Solar Eruption, Zenith or Flying Dragon. Some enemy projectiles can also reveal the shaft, e.g. those fired from the Goblin Sorcerer.
 * The sprite will generate an Enchanted Sword or Terragrim / Arkhalis  upon its destruction. The player can save the game when the shrine is found and force the game to close upon receiving the Enchanted Sword, and can continue doing this until they get the desired Terragrim  / Arkhalis

Trivia

 * Although practically guaranteed in normal gameplay, the shaft can only generate with a height of up to 1000 tiles.
