Runeswarm

Runeswarm is a large construct (Challenge Rating 10).

**AC:** 15 **HP:** 150 **Speed:** [object Object] **STR:** 3 **DEX:** 20 **CON:** 15 **INT:** 2 **WIS:** 12 **CHA:** 18 A cloud of inky runes churns as some of the markings illuminate briefly._ **Untended Runes.** Runes that have gone unused for years or those created on ley lines sometimes gain a modicum of sentience and coalesce into a gestalt known as a runeswarm. The mix of runes flits about in random directions and remains inert except when it encounters living beings. **Early Warning.** Runeswarms trigger their rune randomly, but the runes creating an effect light up moments before the swarms invoke the runes, giving canny observers the chance to prepare for the runeswarms’ effects.
