Castle walls?

[Merry Jolkar]

What is the formula to determine how much damage is done to a castle wall in a siege? Some forts seem impentetrable. The enemy camps outside the walls, sieging them, but they are just too thick. Do the walls get repaired at a rate proportional to the damage they take?

Thanks much, Merry

The answer to this question is (more or less) in the FAQ.

Short Version: The defender's siege ability is subtracted from the attacker's. The result is deducted from the strength of the walls. Castle walls don't "regenerate" unless the siege is lifted (in which case they are repaired fully), or a spell such as Arcane Masonry is used.

Siege ability is primarily based on the strength stat of the unit.

Castle walls will be fully repaired if the siege is broken and the province reverts back to the owner's hands. Castle walls *DO* regenerate if the defender's strength now exceeds the attacker's strength, such as if the attacker withdrew forces, the defender summoned or teleported in more units, the attacker was attacked and suffered casualties, or the attacker attempted to storm with some of his forces and failed.

From Manual Addenda (and a thread somewhere in this forum)

Siege ability is something like ((besieger's strength)² / 100)+bonuses)

Bonuses are +1 for flying units, +1 for city guards

Where the walls of a castle are broken down is determined by adding up the siege and defense factors of the attackers and defenders, respectively.

The base formula for that is the strength of the unit squared, divided by 100. Thus, a unit with 10 strength counts as 1.0, while a unit with 20 strength counts as 4.0. Some units get bonuses and minuses in the final score. For example, flying units get an automatic +1. Sappers get +5 (IIRC). Mindless units get their final score divided by 10 if defending. And some units (like the Man heavy infantry) get a castle defense bonus of +1.

Once the total scores for all the defending and attacking units are calculated, the difference (if the attackers get a higher number) is subtracted from the defense value of the castle. Once that number gets below 0, then the attackers can storm.

What happens if the besiegers are attacked and win? Does the siege continue as before? or does it start over? I ask because when this happens to me, I always get the "We have begun to beseige..." message, even though I started many turns ago. And if nothing else that makes it feel like it is taking longer.

[Norfleet]

If the besiegers are attacked, and defeat the attackers, the siege continues uninterrupted, with one exception: If the attackers included people who attacked by choosing "Break Siege", and as a result, nobody is left in the castle, the castle immediately falls without a storm. This is probably because if everyone charged out of the gates, nobody was left behind to close the gates behind them.

However, if the castle was empty to begin with, and attackers from outside the province failed to lift the siege, the siege continues uninterrupted.
