115: A powerful area-of-effect lightning attack, unleashing surging combat power!

In reality, choosing any of the five elemental attributes was about the same.

The wind attribute could amplify wind Spells; similarly, other attributes would correspondingly amplify their respective elemental Spells.

The reason he chose the lightning attribute was simply because it was the Spell series Lin Yue was most familiar with in his past life.

Opening the attribute panel, he saw that it had undergone significant changes.

Nickname: White Emperor.

Guild: White Jade Capital (Level 5).

Talents: Life Miracle (Supreme-Rank), Heart of Chaos (Supreme-Rank).

Two new attributes, elemental resistance and Elemental Attack, had appeared; these were attributes unlocked only after class advancement, and they were the same for all classes.

After completing the class advancement, Lin Yue checked the class traits of the Chaos Mage. After all, it was a Supreme-Rank class advancement, and he wanted to see how it differed from ordinary classes.

Chaos Mage Specialization (Lightning): When casting lightning Spells, your spell power is increased by 50%. Simultaneously, all lightning Spells will have an additional 10% Spell Lifesteal.

This was simply outrageous.

Lin Yue still remembered the class trait of his first class advancement in his past life.

Lightning Mage: Increases your lightning Spell attack by 5%.

That's right, and that was a Platinum class advancement. Even for a King-rank class advancement, the trait bonus of the first advancement wouldn't exceed 20%.

Yet, a Supreme-Rank class advancement could directly increase it by 50% and even come with 10% Spell Lifesteal.

Calculating it this way, as long as Lin Yue cast a lightning Spell and activated Chaos Power at the same time, his damage would be equivalent to 2.5 times his spell power, and his Spell Lifesteal would reach 40%.

His combat power had more than doubled.

It was truly worthy of being a Supreme-Rank class advancement; Lin Yue's efforts hadn't been in vain.

"Chaos, do you have any area-of-effect lightning Spells?"

After checking his attribute panel, Lin Yue turned his gaze toward Chaos.

Although wild monsters could drop Skill Books, he didn't have that much time to grind right now. Entering the Ruins had already taken over a day, and the Overlord Guild was still waiting for him to deal with them.

He hadn't been in contact with the outside world for a whole day, and he didn't know how things were going on Yun Ruoqing's side.

Therefore, the fastest way now was to learn class skills directly from Chaos.

"Of course I do."

Chaos opened his personal space, which was filled with a dazzling array of elemental skills.

As a True God, the Spells he had accumulated over the years were as numerous as ox hairs. Just a cursory glance made Lin Yue's head spin.

Various powerful Spells appeared one after another; there were even dozens of Forbidden Curse books. Lin Yue even saw Divine Spells, but those skills were too far out of his current reach, so he could only look.

"Well, can you filter them? What lightning area-of-effect Spells can I use right now?"

"Wait a moment. For such low-level Spells, I need to organize them a bit."

After tinkering for several minutes, Chaos opened his personal space again. This time, only two Skill Books were presented to Lin Yue.

Thunder Punishment (Active): 1-Star.

Effect: Release the skill to summon a bolt of lightning to deal damage to the enemy. Simultaneously, the lightning will spread to five surrounding units.

Consumption: 30 MP.

Casting Interval: 1 second.

Requirement: Level 20, First class advancement.

Proficiency: (0/1000).

Thunderstorm (Active): 1-Star.

Effect: Summon a Thunderstorm. The Thunderstorm will cover up to thirty targets within its range every second for a duration of five seconds. Current range: 50 meters.

Consumption: 100 MP.

Casting Interval: 10 seconds.

Requirement: Level 20, First class advancement.

Proficiency: (0/1000).

Two area-of-effect skills, each with its own characteristics.

Thunder Punishment could affect six targets with a casting interval of one second. With Lin Yue's 4.5 Casting Speed, he could cast Thunder Punishment four times in one second, which was equivalent to hitting thirty-six targets.

(Note: I made a mistake earlier. From now on, active skills will use casting intervals instead of cooldowns. There are no cooldown times; Casting Speed will affect the casting interval.)

It didn't seem like many, but this was only the 1-star effect. As the skill level increased, the number of targets would also increase.

Thunderstorm was different; it was an area-of-effect Spell that could instantly cover a 50-meter battlefield, making it very suitable for combat.

With a Casting Speed of 4.5, Lin Yue could release one roughly every two seconds, making it another excellent area-of-effect skill.

However, the only downside was that lightning Spells had relatively high mana consumption. Casting only Thunder Punishment would consume 120 MP per second.

If used alternately with Thunderstorm, he would consume about 340 MP every two seconds, which was 170 MP per second.

With a full set of mana regeneration equipment, he could recover 50 MP per second. Calculating it this way, he would still consume 120 mana per second.

Lin Yue's total MP was only 5800, which meant his mana would be depleted in about forty-odd seconds.

As expected, he couldn't hold onto those attribute points.

After a brief thought, Lin Yue first maxed out his Casting Speed. After the first class advancement, the Casting Speed cap increased by 1.0, and Lin Yue could continue to stack it.

Fifty free attribute points disappeared, and his Casting Speed reached 5.5. The Casting Speed cap would not be lifted again until his second class advancement.

Without much further thought, Lin Yue put all the remaining six hundred attribute points into his mana pool.

One attribute point increased the mana cap by 20 points. His total MP now reached 17,800 points.

Based on a consumption of 120 MP per second, Lin Yue could maintain full firepower for about 148 seconds.

That was two and a half minutes, which was already quite good.

In actual situations, there would be some discrepancies. Finding targets and moving would also take some time. Calculated this way, his current MP could probably support four to five minutes of full-intensity combat.

Five minutes was enough to fight a legion war. Current players were like paper in front of Lin Yue, easily punctured.

With the help of mana potions in between, his combat duration could be extended even further.

Each book cost fifty gold coins. He paid one hundred gold coins to Chaos and learned the two Skill Books.

Chaos brought Lin Yue back to the Temple.

"You have now completed all the quests in the Ruins. I will open the portal to send you out."

After saying that, Chaos began to chant. In the next second, the portal to leave the Ruins opened.
