# Tile modifier events These are events that you typically place directly on tiles in order to add destructables to the map. **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: ![paintdotnet_2017-09-10_01-48-03](https://user-images.githubusercontent.com/19506837/30246509-1df76ac8-95ca-11e7-8eaf-ff68adec8a48.png) - 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. **160: Boss gate** - This block becomes solid when boss mode is activated, and disappears afterwards. **197: Spikes** - Touching this event damages Erina. Damage varies based on background and difficulty level. - Does not need to be on a solid tile to deal damage. **109: Ignore spikes** - Allows Erina to touch certain sides of a spike tile without taking damage. Place around spike tiles as needed. Example: ![paintdotnet_2017-09-10_01-43-46](https://user-images.githubusercontent.com/19506837/30246488-82aa2c2c-95c9-11e7-9d5d-d9fcd978ac52.png)
