|Igniting Standing Stone|
The Igniting Standing Stone is a block added by Roots. It will set fire to all mobs inside its 9 block radius when powered by Redstone. Each 20 ticks (or each second) all mobs inside its radius will set alight for 3 seconds.
The Igniting Standing Stone is created in a Ritual. It requires an Attuned Standing Stone, Glowstone Dust and a Runestone Symbol to be placed on the Casting Altar and one Verdant Sprig, one Infernal Bulb, one Wheat and one Ghast Tear to be burned in the Incense Brazier. The Ritual requires Attuned Standing Stones to be placed around it.
