The third option adds the Bloodlust trait, which allows units with this trait to gain lifesteal when attacking, which currently only has a 10% lifesteal percentage.

Although the bloodsucking effect is quite good, it can provide endurance for summons, but Chen Mo thought that his summons have a duration, and even if the duration is full, it will automatically dissipate, and this endurance effect is basically useless at this stage.

In this way, Chen Mo directly chose the corpse poison effect that appeared several times in a row with perseverance.

[After choosing, please receive the item you crafted!] 】

[This synthesis recipe has been recorded in the recipe list!] 】

Recipe: [Undead Blue] x3 + [Dark Crystal: Rare] = [Poisonous Corpse Orange] (100% success rate)

[In the future, you can directly put in the corresponding materials and directly select the recipe to synthesize the item!] 】

【Poisonous Corps Orange】

[Class]: Skeleton Mage

[Cooldown]: 5 seconds

[Effect]: Consumes 100 energy points to summon 100 skeleton monsters that last for 180 seconds (skeleton monster class is random, and will carry the corresponding class of transformation weapons), skeleton monster attributes are linked to your intelligence and spirit.

The attributes of the skeleton monster you can summon are: HP 100, Physical Attack 30, Magic Attack 30, Physical Defense 0, Magic Defense 0, Characteristics - Explosive Bomb, Resurrection, Corpse Poison.

『Corpse Poison』: Any damage caused by the unit to the target will apply a layer of corpse poison to the target, each stack of corpse poison reduces the target's 1% of all health recovery effects (including natural blood regeneration, taking drugs, bloodstealing, etc.), corpse poison can be continuously stacked, the duration is 15 seconds, and the duration will be refreshed when stacked, when the corpse poison is stacked to 100 layers, a poison explosion will be triggered, causing damage to the target [the current corpse poison stack squared], and it will be triggered every 100 additional stacks in the future. (Poison Explosion damage is poison damage and is reduced by poison resistance.) ）

According to the characteristics of corpse poison, as long as you stack 100 layers of corpse poison on the target, you can directly explode 10,000 points of blood from the opponent, and you can explode another 40,000 points of blood by stacking 200 layers, which can be described as a quite exciting DEBUFF.

Of course, it's not so easy to stack so many layers, and many elites and bosses have the ability to clear anomalies.

However, if there are enough summons and they can all touch the target at the same time, it will be a bit of a sight to behold.

Chen Mo had already seen the effect of corpse poison several times, and his focus was not on this new feature at this time.

"Huh? The basic effect of the skill has changed so much! ”

Chen Mo found that after the skill changed to a medium-grade orange skill, there were some changes in the effect of the skill.

Before, whether it was a white skill or a green or blue skill, it was just a simple summoning of skeletons, the kind of skeleton monsters that had no profession or equipment and could only scratch people with bone claws.

And now the skill has become that it can summon skeleton monsters with professions and equipment, which still surprises Chen Moman.

Before, he was still thinking that even if he summoned a large number of skeleton monsters, but considering the effective attack range, the skeleton monsters on the periphery were not enemies that could not touch the center.

But if there are archers, mages, skeletons, and monsters, this is not a problem.

With the change of the basic effect, the attributes of the skeleton monsters that Chen Mo can summon have also changed accordingly.

In the past, skeleton monsters only had physical attack attributes, but now they have more magic attack attributes.

Of course, the defense is still as good as ever.

"The middle grade is the middle grade, and the improvement compared to the low grade is not a little bit at all, no wonder the price of the middle grade is not cheap!"

Seeing that the orange skill had improved so much, Chen Mo continued to strike while the iron was hot and began to combine the yellow skill!

However, this time, it will take some time to prepare in advance.

After all, he's going to merge two orange skills all the way from white.

The bundle of skill books in front of Chen Mo dropped in height at a speed visible to the naked eye.

A yellow skill requires eighty-one white skill books to synthesize.

Chen Mo bought a total of about 100 copies, and only a small part of it was consumed at once.

Finally ready, Chen Mo threw the three highly poisonous corpses into the synthesis column with a look of anticipation.

…… You have placed [Poison Corpse Orange]*3!

……

[The quality of this synthesis is medium quality, and you need to add an additional special material - Dark Source Stone - Rare]

As expected, with the formula testing, the dark source stone that Chen Mo bought in advance was indeed the key material for the Yellow Skill Book.

Chen Mo directly threw the prepared Dark Source Stone into it.

Soon the results came in.

[Congratulations, the synthesis is successful!] 】

[Please choose one of the three composition options below as the final composition result!] 】

[1]: Hidden Corpse Army: Yellow (Bind)

[2]: Giant Corpse Army: Yellow (Bind)

[3]: Blood Corpse Army: Yellow (Bind)

"Good guy, just reach the fifth level skill, and you can summon the army of the undead!"

Chen Mo couldn't wait to check the effect of the skill.

Sure enough, the so-called army is really not covered, and it can actually summon five hundred skeleton monsters at once.

That's a staggering amount!

Chen Mo didn't dare to think about what kind of scene this undead army of five hundred skeleton monsters summoned at one time was.

After taking a look at the number of summons, Chen Mo set his eyes on the three new effects.

It is said that it is a new effect, but two of them are familiar faces.

The Hidden Corpse Army increases its stealth ability, which allows the Skeleton Army to be invisible when not attacking.

The Blood Corps is an upgraded version of the Bloodthirsty Corps just now, and this time the bloodsucking ability has been increased by 20%.

These two familiar faces, Chen Mo swept over directly and looked at the army of giant corpses in the middle.

"The second option will actually reduce the number of summons by ten times, although the size of the skeleton monster has been increased, some attributes have been further strengthened, and a lot of combat effectiveness has been improved, but I would rather choose the number than ten times less.

The speed at which five hundred skeleton monsters stack corpse poison is not comparable to that of fifty skeleton monsters. ”

Chen Mo directly shot the second option, this effect of reducing quantity for quality, he didn't want it at all.

In this way, it can only be one of the three.

This time, Chen Mo didn't bother too much, he directly chose the army of hidden corpses!

When the stealth ability first appeared before, Chen Mo wanted this ability a little.

The way to use the army is to take it by surprise, and if an army of hundreds or thousands of people breaks into the enemy's rear without knowing it, the effect of the blow is quite deadly.

The stealth ability seems to have no effect on the actual output effect, but it is very strategic, and it is really useful in actual combat.

After consuming only eighty-one worthless white skill books, Chen Mo easily mastered a priceless and unmarketable superb yellow skill.

At this time, he was only level 1, if he let others know, he would not think that Chen Mo was the illegitimate son of a high-ranking person in a big family.

Because it is impossible for ordinary people to master such high-grade skills at level 1!
