After randomly assigning the location of the flooding, another die roll is made on the Moderate flooding line with a 9 result, causing an PX hit to the battleship. Note that a shell may not inflict any flooding if its size rating is less than one-quarter of the size rating of the target vessel. If required to roll for possible sinking due to flooding, locate the number on the Total Flooded column which matches the total flooding points present on a vessel and roll one 12 sided die. If the number rolled falls within the corresponding range called out under Sink Roll, the vessel has begun to sink. See the Sinking portion of the Damage section.
Cyclic effects are part of the basic fire and flood rules.
Their ongoing presence on board a vessel constantly threatens to trigger more damage. Static effects are damage events which cause various types of specific damage all at once. To conduct a critical effects roll, roll one die and cross-reference its value to the applicable critical effects line. The values shown on the Damage Control Chart are those which need to be rolled on a 12 sided die in order to repair damage to the corresponding damage types. If either vessel if moving away from the other in any way, they are considered to be on diverging courses.
