You might have fun freezing somebody in a PvP zone

My take: The only real use for this trap is to immobilize the mobs that spawn with boss monsters.  If you plan on getting this boi gold or freezing trap, get sandman.

Freezing Trap (hidden trap): Freezing trap causes monsters to freeze at a chance and damage is also dealt when stepped on. Boss monsters are not affected.

My take: You might have fun freezing somebody in a PvP zone, but it's not too useful since the enemy will break free once you hit them again.

Blast mine (visible trap): Blast mine is a grenade type of mine, it has a given time period and it explodes when time expires, also damages surrounding monsters within 9 cells. Deals fire property damage.

My take: Fire element is one of the better elements and this trap deals a good amount of damage as well. I would prefer this trap over landmine because I don't like earth property, but it's your choice.

Claymore Trap (visible trap): Deals fire property damage in a blast radius of 25 cells. Int increases its damage.

Steel Crow (passive): Steel Crow increases the attack strength of your falcon.
