# Tile modifier events

These are events that you typically place directly on tiles in order to add destructables to the map.

If a block disappears, any collision attached to it also disappears. Conversely, if a block appears, then any collision attached to it will only take effect after it appears.

- **[1] Wood block**
  - Block can be destroyed by hammer attacks.

- **[2] Bomb block**
  - Block can be destroyed by explosives.

- **[3] Bomb chain block**
  - Block can be destroyed by explosives, and will cause a chain reaction with other blocks with event 3 on them.
  - The chain reaction doesn't need to be on solid tiles, and will follow the path set. Example:

  - The chain will follow all event 3 blocks despite only having two blocks to destroy along the way.

- **[6] Fairy block**
  - Block can be destroyed by Ribbon shots.

- **[7] Ice block**
  - Erina will destroy these blocks on contact if she has the Fire Orb.

- **[8] Cracked block**
  - If Erina steps on this block, it makes a snapping sound, then disappears a short amount of time later.
  
- **[30] Low Item% block**
  - These blocks are only visible in Low Item% mode. Upon reaching 10% item collection rate, they disappear.

- **[160] Boss gate**
  - This block becomes solid when boss mode is activated, and disappears afterwards.

- **[108] Rainbow Crystal gate**
  - This block is solid until defeating the Rainbow Crystal boss.

- **[110] Pandora gate**
  - This block is solid until defeating Pandora. If Pandora is defeated on the same screen, this block remains solid until leaving the screen.

- **[455] Keke Bunny gate**
  - This block disappears and re-appears during certain attacks used by Keke Bunny.
