How it works

The Communications Tower raises a glowstone spire that gives everyone nearby a shared channel of speech. Set a key block above and below the glowstone, then right-click the glowstone. The scaffold burns away and a column of glowstone rises, taller at higher Tiers.

Players within its reach share a chat channel named by the two key blocks, the same kind of channel a Runic Radio pearl uses.

Tier	1	2	3	4	5	6	7
Height	18	36	54	72	90	108	126
Reach	8	16	24	32	40	48	64

Good to know

• The sky above the glowstone must be clear for the tower to rise.
• Right-click any glowstone in the column to power the tower down to its base, and again to raise it.
• Breaking any block of the column brings the whole tower down, leaving a single glowstone.

Configuration

These are the defaults in plugins/Runic/runes/communicationstower.yml. Every rune file also carries the shared settings described in Rune files.
