Artifact Acquisition

Artifact Quality

The base quality of an artifact, bounded from 0-100, affects the artifact’s effect RNG rolls and numerous smaller factors. It is displayed in the bottom left corner of each artifact in the inventory.

Obtainment

Post-Game

After a game ends in a win, an tetromino-type artifact is granted with quality based on the earned xp.

Procedure:

  1. Random tetromino artifact (IJLOSTZ, equal chance) at level 1
  2. Use xp gain from gamemode (20 for puzzle mode, score/100 for scoring modes)
  3. Base quality = sqrt(xp) * 2.5
  4. Bound base quality between 0 and 100
  5. Roll effect based on base quality

Note that only level 1 artifacts can be obtained post-game.

Fusion

Five artifacts are sacrificed to create another artifact with a randomly generated base quality. These artifacts all must be the same level.

Procedure:

  1. Randomly select a sacrificial artifact and use its type (I,J,J,J,O = 20% chance for I, 60% J, 20% O)
  2. For each sacrificial artifact, randomly multiply its base quality by 2 or 0.8 (50/50 chance)
  3. Define final base quality as b, randomized sacrificial base qualities as b1, b2, b3, b4, b5, random value from 0-10 as r
  4. b = (b1+b2+b3+b4+b5)/5 + 20 + r
  5. If final base quality > 100, increase level by 1 and randomly set base quality to a number between 30-50
  6. Reroll effects based on base quality
