Also, goblin artisans seem to have special abilities.
The defense towers repaired by them have even higher durability than before.
On average, it can increase by 30%...
I can't take care to lament the ability of goblin craftsmen.
Facing a defense tower in front of him, Qiao Shan patted the torn upgrade scroll directly.
"Wow~"
The scroll was close to his body, and the defense tower in front of him instantly lit up.
A ray of light enveloped the defensive tower he photographed.
Fire Element Wooden Arrow Tower!
At the very beginning, Qiao Shan used the fire element to bless the scroll to create a fire attribute defense tower, which is at the second level at the moment.
Qiao Shan was the first to choose to upgrade it.
He has already identified his surroundings as a forest.
And the rocket tower, in the forest environment, the attack power is very powerful.
The second-tier Fire Element Wooden Arrow Tower cannot be upgraded with ordinary wooden arrow towers.
Qiao Shan chose to upgrade it with an upgrade scroll.
As the light receded, this Tier [-] Fire Elemental Defense Tower, which had made great achievements, immediately underwent a major change.
The volume came to four or five meters high.
The bottom of the tower reached a diameter of nearly two meters.
A series of burning flames were engraved on the perimeter of the defense tower.
Even the surrounding environment has brightened a lot.
A four-tier fire element wooden arrow tower like a visitor from hell.
Appeared in front of Qiao Shan.
With a bright light in his eyes and a raised eyebrow, Qiao Shan opened the attribute bar of the fourth-tier Fire Element Wooden Arrow Tower.
【Fire Element Wooden Arrow Tower
Grade: Fourth grade
Range: 400 meters
Attack speed: 1 seconds/time
Attack: double arrows, attack power 80-150 (can be anti-air)
Rapid Fire: The attack speed is increased to 0.5 second/shot, the duration is 1 minute, and the cooldown time is 10 minutes.
Elemental blessing: Each arrow is blessed with fire elemental attack, increasing the attack power by 20 points, and can form a flame attack on the corresponding monster.
PS: Continue to upgrade, there are big changes...
】
Unsurprisingly, the fourth-tier fire elemental wooden arrow tower also has double shooting and anti-aircraft capabilities.
Not only has the attack power been doubled several times.
Moreover, the attack power of the fire element blessing has also increased to 20 points.
Of course, if [Prompt Sound] lures Qiao Shan and continues to upgrade the defense tower to the fifth level, it still exists.
pity….,
This special tower upgrade is too troublesome.
To upgrade to Tier [-], it seems that you have to get the Tier [-] "Unlimited Defense Tower Upgrade Scroll".
If you are unlucky, this may have to wait until the Year of the Monkey...
"Next!"
However, he didn't worry about the fifth order.
Tier [-] is enough for now, Qiao Shan chooses to continue to upgrade other towers.
Soon, he got a fourth-tier special tower.
【vine tower
Grade: Tier [-]
Category: special tower
Range of action: 400 meters
Efficacy: Send out a powerful vine, bind a monster for 10 seconds (no decay).
Double Pull: Two vines can be issued at a time.
Pull back: Bind a monster and pull back 100 meters, once a minute.
PS: Control two at a time, this is called dual control.
】
The second scroll was used by Qiao Shan on the vine tower.
This is a defensive tower he specially built in order to pass the boss round.
With the blessing of the scroll, it directly changed from Tier [-] to Tier [-].
Compared with the first-tier and fourth-tier vine towers, the attack distance and binding time are much improved.
The biggest change is that it can send out two vines at a time.
Get a double clapper.
On the fourth-tiered vine tower, there were two dark vines that were as thick as thighs.
There was still a blue light on the vines.
Faintly bright.
Without testing his ability, Qiao Shan quickly tore open the third scroll.
With a flash of light, another special tower was upgraded to the fourth level.
【Poison Mist Tower
Grade: Fourth grade
Range: 400 meters
Toxic mist range: 50 meters
Damage: 10/sec
Poison mist attack: Release a piece of poison mist to attack monsters within the range of the poison mist, lasting for 20 seconds (once a minute)
Weakness Attack: The poisonous mist can automatically find the monster's weak point and erode it.
PS: You enter and you die.
】
Tier [-] Poison Mist Tower, the best choice for blood reduction.
Regardless of whether the monster is of the type of sea, land or air.
The debuff damage of the poisonous mist is always very strong.
And the longer the time, the greater the damage.
Poison Tower!
A very specific type of defensive tower.
At this moment, the poison mist tower of the first level was upgraded to the fourth level by Qiao Shan.
Inside the four-step tower, a transparent container like a poison jar appeared.
The green mist is lingering inside, and it is very scary to look at.
"This tower needs to find a chance to move its position..."
The appearance of the poisonous mist tower made Qiao Shan decide to find an opportunity to move the tower farther away.
It looked too dangerous.
Such dangerous things must be kept away from residential areas.
If something goes wrong, it will be a big trouble...
……
Chapter 50 Living in a stone house
After the Poison Mist Tower, Qiao Shan upgraded the "Sentry Tower" and "Lure Tower" successively.
These two special towers were developed by himself.
One is the second wave and one is the seventh wave.
The sentry tower can provide vision, and it is said that after a high level, there are advanced abilities such as breaking the hidden.
And the lure tower is a target tower.
The blood is so thick that it has a durability of 1000 at the first level.
After being upgraded to Tier [-] by Qiao Shan, his blood volume immediately exploded.
After the last two special towers were upgraded to the fourth tier, Qiao Shan quickly went to check the changes of the fourth tier sentry tower.
【Watch Tower
Grade: Fourth grade
Category: special tower
Durability: 400/400
Range of action: 500 meters
Efficacy: Dispel darkness and provide vision.
PS: After upgrading to the fifth level, you will have what you want.
】
"All right!"
After seeing the fourth-order sentry tower, only the range of action and durability have been increased by four or five times, and there are no other changes.
Qiao Shan was a little helpless.
He expects functions such as breaking stealth and positioning.
The fourth-tier sentry tower did not appear.
According to the [Prompt Sound], it should be at the fifth level.
Unfortunately, the fifth step is far away.
No one knows when there will be a fifth-order scroll...
The sentry tower was not satisfactory, and Qiao Shan looked at the last upgraded Tier [-] defensive tower.
【Lure Tower
Grade: Tier [-]
Category: special tower
Range of action: 4000 meters
Lure: Send out a wave of lure to attract monsters to attack the lure tower first.
