Even with a single drop of blood, I will still be invincible!

You have obtained the C-rank skill book "Summon High-Level Skeleton".

Even after fusing the three skill books, it's still only a C-level skill; the only difference is that you can choose the type of skeleton summoned each time.

The casting time, mana cost, and cooldown time are all the same as Su Mubai's Summon Skeleton Warrior, with no changes whatsoever.

Comparatively speaking, the skill fusion did not enhance the skill; in fact, it weakened it slightly.

Because originally, you could summon three high-level skeletons within 30 seconds using three skills, but now you can only summon one.

Its only advantage is that it only occupies one skill slot.

Su Mubai didn't care about this. With the SS-level Death Summoning, his skill cooldown was only two seconds.

With a single thought, I chose to study.

[Hint: You have learned the new skill "Summon High-Level Skeletons". The original "Summon Skeleton Warriors" skill in your skill bar will be replaced.]

"It happened!"

Upon hearing the system notification in his ear, Su Mubai's expression changed.

Is "Summon Skeleton Warriors" overwritten?

Does that cataclysmic feature still exist?

Before he could even open the skill menu, a system notification sounded.

[An unknown term exceeding the limit was detected for this skill. Complete overwrite failed; the unknown term is retained.]

【Summon High-Level Skeleton】: (C) Level 1, Active Skill, summons a skeleton warrior/skeleton archer/skeleton mage to fight for you.

Cast time: 3 seconds; Cooldown: 30 seconds; Mana cost: 300.

[Catastrophe Characteristics]:

1. Skeleton Warrior's maximum health is increased to 500%, and attack power is increased by 100%.

2. Not enabled

3. Not enabled

(The advanced skull panel is affected by the player's Spirit attribute.)

"Phew~ thankfully it survived."

Looking at the skill description, Su Mubai breathed a sigh of relief.

As expected of a talent that transcends limitations, even the system cannot fully cover it.

The other two unactivated Cataclysm traits should correspond to Skeleton Archer and Skeleton Mage, respectively.

To activate it, you must use the "Cataclysm" skill on the "Summon High-Level Skeleton" skill.

After overwriting the original skill, it means that Su Mubai can get it for free again.

Selecting the new skill, Su Mubai had a sudden thought.

[Catastrophe]!

[Objective: Summon high-level skeletons]

[Hint: Please select the promotion rank: Tier 1/Tier 2/Tier 3.] (Click to view details)

The game seems to be constantly being improved; now, the prompt after using [Catastrophe] includes a "View Details" option.

Option 1: Upgrade to Rank B skill [Summon High-Level Skeleton], no cost.

Option 2: Upgrade to Rank A skill [Summon Elite Skeletons], costing 10000 gold coins.

Option 3: Upgrade to S-rank skill [Summon Skeleton Army], consuming 1000 years of lifespan.

"level one."

No choice at all.

Su Mubai had neither ten thousand gold coins nor a thousand years of lifespan.

What can relieve worries? Only freebies!

Your C-rank skill "Summon High-Level Skeleton" has been successfully upgraded to B-rank.

The name hasn't changed, and the summoned skeletons are still the same three types, except that summoning one at a time has been increased to summoning three at a time.

The cost has also increased to 1000 mana points.

Even if a low-level necromancer learns this skill, they won't be able to use it more than a few times.

After all, not everyone has such a high level of magical power as Su Mubai.

After the original skill was overwritten, all skill points were returned, and Su Mubai immediately added all 8 skill points to [Summon High-Level Skeleton].

This skill was immediately upgraded to level 9, and a Max icon appeared in the skill icon, indicating that the skill can only be upgraded to level 9 at most.

In the game "Multiverse", players gain one skill point each time they level up.

However, the skill points required to upgrade skills of different grades are different, and the maximum level is also different.

According to Su Mubai's observation, skills below grade A only require 1 skill point to upgrade each time.

Grade A requires two points, and Grade S requires five points.

After the skill 【Death Absorption Feedback】 is promoted to SS level, the skill points required for upgrading it also increases from 5 to 10.

As for the higher SSS-level skills, Su Mubai was still unaware.

It is estimated that at least 20 skill points are needed to level up.

Upgrading skills consumes so much resources, there must be other ways to obtain skill points besides leveling up.

Su Mubai's [Cataclysm] talent can retain the original level of skills, which can save him a lot of skill points.

Reggie dropped two more skill books. [Thunder Strike] is a skill for warrior classes, which Su Mubai cannot learn.

However, another book, "The Halo of the Dead," greatly enhanced his abilities.

You have learned a new skill: "Aura of the Dead".

The skill book transformed into a stream of light and flew into Su Mubai's brow, and a pale gray halo immediately appeared beneath his feet.

With a thought, the halo disappeared instantly, but the effect remained.

This is an aura-type passive skill, with the same effect as Reggie's, which increases all attributes of friendly undead creatures by 20%.

After glancing at the skill description, Su Mubai had an idea.

[Catastrophe]!

[Target: Aura of the Dead]

[Hint: Please select the promotion rank: Tier 1/Tier 2/Tier 3.] (Click to view details)

"level one."

Without even checking, Su Mubai knew very well that he couldn't be promoted, so he decisively chose to advance.

Your Rank B skill "Aura of the Dead" has been successfully upgraded to Rank A skill "Advanced Aura of the Dead".

[Advanced Aura of the Dead]: (A), Passive Skill.

All friendly undead creatures gain a 30% increase in all attributes.

Impact range: 500 meters.

The attribute increase was only 10%, but the range of influence increased from 100 meters to 500 meters.

This has already exceeded the maximum distance that Su Mubai can currently control his summoned creatures.

Furthermore, with the added benefit of the profession's catastrophic characteristics, this range has been expanded to an astonishing one thousand meters!

hum~

Su Mubai waved his wand, and a three-meter-high light gray vortex appeared beside him.

The mana value instantly dropped by 1,000, and six skeletons emerged one after another.

The six of them look exactly the same as the ones Reggie summons, and they are even more imposing!

However, Su Mubai did not rush to check the skeleton's attributes.

After changing their outfits, the stats of all three skeletons will be significantly improved.

There's no point in looking at it now.

What he needs to do now is to fill the summoning space first.

Because the Cataclysmic feature is not fully realized, the Skeleton Warrior is significantly more powerful.

But Su Mubai couldn't just summon skeleton warriors.

After all, with the existence of unit volume collision, the skeleton warriors simply cannot unleash their full combat power when facing too many BOSSes.

Ultimately, Su Mubai decided to use a 4:3:3 ratio for the ingredients.

Next, all that remained of the items Reggie dropped were some materials and the crystal ball that Su Mubai cared about most.

You have obtained 10 Dark Gold-grade material, Deathly Bone.

You have obtained 10 Soul Remnants, a Dark Gold-grade material.

Su Mubai didn't rush to advance his career with the two materials; instead, he simply tossed them into his backpack.

His attention was entirely focused on the final crystal ball.

In the dim light, Su Mubai seemed to see a faint shadow inside the crystal ball.

You have obtained the quest item "Harrens' Crystal Ball".

The moment the crystal ball was in his hands, a system notification sounded in Su Mubai's ears.
