Chance of a base siege
The master switch for attacks on large bases. 0 turns them off, 100 makes them the rule.
scum.BaseBuildingEncounterTriggerChance=-1.000000
What does this setting do?
Once a base has grown large enough, the game can start a siege: sentries move in and attack the compound. This value is the probability in percent that it actually happens.
The default -1 does not mean zero but “use the game's default”. If you want a number you can rely on, write it out – and to get rid of sieges altogether, set 0.
This is the value to reach for first, because it decides the event as a whole. Only once it should happen is it worth tuning the damage values. Conversely there is no point setting all three weapon multipliers to 0 when a 0 here saves the whole effort.
Whether the check runs at all depends on element count: a base has to reach a minimum size before it counts as a target. Small huts are therefore never besieged, however high this value stands.
Which value suits my server?
0 to 25. Appealing as a rare event, not as a permanent state.
-1 or 50. Large bases should cost attention.
75 to 100. Build big and you get attacked.
What to watch out for
The default -1 means “game default”, not “off”. To disable sieges you have to enter 0.
Without the minimum element count no check runs at all. Small bases stay untouched even at 100.
