Destroy is the action used to break structures. Destroying structures drains drains Phlegm. Structures take % damage while being Destroyed, once the structure reaches 100% damage it will break. The % damage done is related to your remaining Phlegm and that structure's Soak Value, so your rate of destruction slows down as your Phlegm is drained. Attempting to Destroy Claimed stuctures is a Crime and will leave Scents and summonable Evidence of Waste. Being inside a Building when is it Destroyed will cause you to become instantly Knocked Out.
Can Be Destroyed:
High Soak Structures
High Soak Structures are structures which require a minimum amount of Phlegm in order to fully Destroy it. Having less Phlegm, or falling under that base amount due to drain, will cause the structure to take less and less damage until the damage falls off completely. With the exception of Wall this minimum value is 1000 Phlegm. However, these high Soak Structures can be Destroyed using Greek Fire. Using Salvage, when it is possible, will ignore Soak.
Alternate Methods of Destroying
Certain stuctures require an alternate method to Destroy them due to the high investment in building or maintaining them.
