Fortifications and siege spells

Fortifications are raised in the Muster Hall like units but never leave their stronghold. They fight in every battle at home, alongside the units stationed there.

• After a battle, about 70% of the fortifications destroyed are rebuilt for free: each one has a 70% chance when 100 or fewer were lost, and 60% to 80% of them come back when more were lost. With the Master Mason, half of the remaining losses are restored too.
• Fortifications that are not rebuilt leave spoils only if the world's charter says so (0% by default).
• The Ward Domes are limited to one of each per stronghold.
• Fortifications use the defender's war disciplines and kindred bonuses, like units.

Siege spells

The Counterspell and the Meteor Spell are crystals stored in the Spell Battery, which holds 10 slots per level. A Counterspell takes one slot and a Meteor Spell two. Spells never fight in battles, cannot be stored on a Skyhold, and are raised in the Muster Hall like fortifications.

Casting Meteor Spells

From the map, open a rival stronghold and cast Meteor Spells at it:

• The target must be on the same continent and within your range: 5 × Beastmastery − 1 provinces.
• They fly for 30 seconds + 60 seconds per province between the two strongholds.
• Each Meteor Spell carries 12,000 might, raised 10% per Weaponsmithing level of the caster at launch.
• They destroy fortifications only. You may pick a primary target; the meteors smash as many of it as they can (each needs its full fortitude, with the defender's Armoursmithing), then move on to the other fortifications in order.
• Each Counterspell in the target's Spell Battery unravels one incoming Meteor Spell and is used up.
• Casting counts as an attack, so protections apply: no casting on a realm in Sanctuary or on a protected fledgling, and while you are a fledgling yourself you cannot cast on a lord with more than five times your renown.

Both sides receive a report of the strike.
