Raises a sphere of refusal: hostiles are turned away — or all are, save those carrying the key. A solid secondary Tier block starts it; last fuel sets how long it holds. An Aether Chest can feed it after.

How it works

A Force Field raises a sphere of refusal around its totem. The Tier blocks in the column set its radius, from 16 blocks at Tier 1 to 64 at Tier 7. A second Tier block, seated in the floor centre, is its fuel: it is consumed when the field rises and decides how long the field holds.

Right-click the redstone torch on top to raise the field:

• With an empty hand, it keeps hostile mobs out. A force field hums — hostiles kept at bay (32 blocks, 145s).
• Holding an item that cannot be placed, such as a stick, it keys the barrier to that item. Only players and creatures holding the same kind of item may stay inside, and everyone else is pushed out.

Right-click the torch again to lower the field.

Fuel

The fuel's own Tier sets the field's time, whatever the Tier of the column:

Fuel Tier	1	2	3	4	5	6	7
Lasts about	1½ min	1¾ min	2½ min	16 min	74 min	2.9 hours	28.6 hours

When about one second remains, the field drinks again to keep itself up. It draws first from a Qixsilver Reservoir in your Domain, then from an Aether Chest in the fuel seat, then from a fresh Tier block placed there. The force field drinks the offering (+93s). The first raise always needs a real Tier block in the seat, since an Aether Chest cannot start the field.

Configuration

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