>>47257105Beacons give a buff to players within their range. The pyramid's size increases the availability, power, and range of the buff. Mining speed, player movement speed, attack strength, damage resistance, jump height, and health regeneration can be buffed by a beacon
The pyramid can be made out of gold, iron, diamond, emerald, and/or netherite blocks. What material(s) you use to make the pyramid has no affect on the buff. Creating a beacon fully out of netherite blocks is purely just to show off.
However, Kaela is thinking too small here. To get all six, full power buffs a beacon can provide, you need 6 beacons. The actual beacon block can share pyramid structure with other beacons. That's not good enough. Kaela should make six full Netherite beacon pyramids.
