Your soldiers and ships take no damage.

Other players' soldiers and ships die from one hit.

Your buildings take no damage.

Your mana never drops below the amount here whenever the game reads it.

Your workers drop a full load (the amount here, or the sawmill amount at a sawmill) each time they set down goods.

Your building sites need no levelling, so builders start at once.

Your building sites' three resource counts are capped at 1 as they are written. Hold Left Ctrl while that happens to put the amount here into the first one instead, or Right Ctrl for the second. The table calls it bEnableBuildResOverride.
