Redstone

Circles that read or write redstone signals. Most use a bound item, set by right-clicking it onto the circle, as their setting. Higher levels generally widen the reach or range; the table below has the mana for each.

• Redstone Mana gives out a signal from 0 to 15 for how full your mana network is. It only works on a mana block. Bind a Mana Gem to set what a full signal means.
• Redstone Timer pulses on a schedule: bind redstone for ticks, sugar for seconds or glowstone dust for minutes, with the stack size as the count. Level 1 pulses the block it is on. Level 2 and up pulse every block that can carry a signal in the disc around it. With nothing bound it does nothing.
• Redstone Sensor counts what is in the same area a Trap of its level covers and outputs 0 to 15. With nothing bound it counts every living thing, players included. Bind armor to count players, a sword for hostile mobs, an egg for peaceful animals, an emerald for villagers, or an item a mob drops for that mob. Any other item counts dropped items of that kind; a block counts nothing.
• Redstone AoE is the sensor made into a pressure-plate field: the block under each match outputs 15 instead of the circle's host.
• Redstone Link carries a signal between circles. Links bound to the same item are one wire. The block it sits on is the input and the other five faces are the output. Level 1 hears its own dimension, level 2 hears every dimension.
• Redstone Latch is a toggle. Each rising signal on the input flips the output on or off, and it remembers its state across restarts. Green is on, yellow is off.
• Redstone Counter is a pulse divider: every Nth rising signal makes one pulse, where N is the size of the bound stack (nothing bound means 1).
• Redstone Stock reads how much of the bound item your storage network holds, from 0 to 15. The stack size is the amount that counts as full. Cast on a chest that is not in the network, it reads that chest alone.

Any circle can also be paused to save mana: a lever, button, torch, repeater or other redstone component powering the block it is drawn on stops it, and a paused circle costs nothing. Plain redstone dust running into the block does not pause it.
