Map Hazards
While exploring the various levels of the Clockworks, Knights will encounter many dangers besides monsters. Most hazards can only be found in appropriately themed levels, but others like floor spikes can be found in almost all of them. Knights will take damage and sometimes even status effects by walking into certain hazards and should avoid them at all cost!
Floor Spikes
Floor spikes are the most common hazard encountered by Knights and should be avoided by all cost. They inflict piercing damage and can often break a Knight's shield before they retract back into the ground.
Thorns
Thorns are mostly found on grassy levels and are in fixed positions. Thorns pose most of a threat when an enemy is knocked into the middle of a patch of them, in which case ranged attacks are needed to reach them. Monster drops have a bad habit of hiding in the middle of this hazard.
Poison Thorns
Poison thorns are exactly like regular thorns except they will give you the poison condition.
Fire grate
Fire grates are only found on flame levels and, like floor spikes, is only dangerous for a short period of time. Getting hit by this hazard will ignite you with the fire condition.
Fire pit
These can be found when traveling in the Firestorm Citadel. Unlike fire grates, fire pits are a constant hazard and should be avoided at all costs.
