PDA

The PDA is a accessory that gives helpful and informative information to the player. The PDA displays fishing information, weather, moon phase, elevation, distance east/west, time, nearest valuable, player speed, current DPS, number of monsters killed, the name of the rarest nearby enemy, critter or bound NPC, and nearby enemies. Just like the Ankh Shield, this also has a very long crafting tree which is explained here for your support.
