Overlord: Start from the Goblin Lair

Weak healing potions are not the most useful even as a treatment method, but they are cheaper. But in Ron's hands, it was used in a different way.

"Materials." Ron took a step forward, pulled out the cork on the potion bottle, turned his wrist slightly, and poured the entire bottle of potion onto the ground.

A red light flashed in the little eyes of a rat assassin, and he instantly rushed towards Ron who poured the potion. At the same time, the soil under his feet became wet. However, when the dagger in his hand was like a whirlwind, it shattered the person in front of him into pieces. All it hits is a mirror image.

"Action." Ron stretched out his hand and patted the assassin on the shoulder. The opponent wanted to turn around and strike, but it was too late.

Ron's lips moved, and he quickly recited a strange incantation that did not belong to this world. The rat-man assassin felt an inexplicable heat from the soles of his feet to the sky. The next moment, a plant as tall as a person grew out of the soil. The trees formed by the gathering of pure arcane energy enveloped the Rat Man from top to bottom.

"Squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak, squeak. The compatriots who are under control may even directly kill this mage who has exposed himself without knowing the heights of the world!

But Ron consumed a complete third-level spell slot, not just to control a single enemy through contact.

When he saw a group of rat men rushing toward him, Ron's mouth showed a smile, and he activated the Lost Tracks. His figure appeared behind the team in an instant, and a flame in his hand The arrow also accurately hit the rat assassin who was unable to dodge because he was controlled.

"Bang!" Ron's own voiceover was submerged in the violent explosion. The coverage was far inferior to the fireball spell, but the terrifying explosion with comparable lethality filled the entire cave, and the high-temperature tongue of fire licked Ivy's body. He raised the tower shield and retracted his claws towards the instigator Ron with hatred.

But the rat people at the center of the explosion were not so lucky. When the temperature in the cave dropped slightly and the smoke gradually dispersed, two digits of charred corpses were lying on the ground where Ron had stood before, and the soil below was When cooked, some of the materials inside even turn into glass. Its high temperature and destructive power are evident.

"Let me guess... did you refer to the fireball technique and vampire touch?" Sylvia walked to the front of the mess, stretched out her finger and touched the hot ground, "But how do I remember what the elf mage wanted to achieve? Is it a protective spell?"

"So I just had some ideas," Ron blinked. In fact, the explosion and his wandering steps were almost synchronized, and the terrifying high temperature burned his eyes. "I didn't do it. I understand how he protects himself, but I changed my mind."

"Since you can't protect yourself, why don't you just release yourself?"

"The raw materials contained in the potion are flammable in nature, and coupled with the alchemical tricks included in it, as long as you do a little processing during the casting process, you can get portable casting materials."

"However, during the previous experiments with the beast, the target would always move around, so in order to stabilize its range, I had to choose to add additional actions and use contact casting - the advantage of this is, I can control its explosion range stably to ensure no accidental damage.”

"The price is that you have to pay a step of confusion - not counting the mirror shadow spell and the haze spell," Sylvia smiled and said, "If you want to further perfect this spell, the benefactor still has a long way to go. Woolen cloth."

"How about you try to cast spells while wearing armor like me?" Victoria showed Ron the armor she was wearing. "You can enchant the inner lining to protect against fire, which will be much more convenient."

Casting spells while wearing armor is a good choice for lone wolves and spellcasters in the army. However, Ron feels that he does not have the need for this aspect yet. After all, it is only a semi-finished product. If he gives himself some time to perfect it, it should not be necessary. It takes so much trouble.

"It's a pity that I can't learn this thing," Ivy kicked the half-human, half-rat meat that was roasting deliciously on the ground. "Speaking of which, you can use any healing potion to cast spells, right?"

"The strength of the spell depends on the strength of the potion," Ron nodded. "If a conventional healing potion is used as a casting material, the explosion level is the same as that of the fireball, but isn't that meaningless?"

In this kind of terrain, the fireball technique can damage the enemy by a thousand, and the self-damage may also be a thousand. It's not like they haven't experienced this firsthand. In contrast, delicate and controllable explosions are more suitable for such occasions.

"Can it be used on dead objects?" Sera licked her lips, and the barbarian suddenly had an idea. "I think just now, a tree appeared on the ground to control the rat man, right? Can you use something else instead? ——”

She made a throwing gesture with her Canglan Grip, which made Ron's eyes widen.

"Sera, you are simply a genius!" Ron slapped his thigh, "Quick, rush in, there must be rat people inside, I saw some of them running away with a few giant rats!"

"Follow me, I need to know the answer!"

With Ron's explosion, the status of both sides suddenly reversed: the ratmen fled to the depths of the cave in fear. The casters who could cast large-scale killing spells were no longer something that they, the ambushers, could handle; while Ron and his companions continued to pursue, picking up the weapons and traps abandoned by the ratmen from time to time as experimental subjects, and throwing them at the backs of the fugitives in front.

With a "bang", a ratman cut the rope in panic, and a huge stone door fell down, blocking Ron and his companions outside their nest.

But can this stop them? No!

"Only a large enough volume can achieve the effect," Ron "wasted" another bottle of potion, and signaled Sera to knock a stone more than one meter long from the surrounding stone wall, "Put it here, and pull it up and throw it over when you see it covered with energy later!"

The entanglement of the trees rooted in the ground is a visual effect. Only the target is controlled and unable to move, and others can still move the recipient normally.

"But even if it can be used this way, it can't be compared with the regular fireball spell," Ivy held her knees and panted slightly. These guys chased her like this without considering her feelings at all! "Isn't it more cost-effective to use the fireball spell?"

"No, no, no, you're wrong," Ron grinned, "For living things, you need to control the target and prevent it from moving freely, but for dead things, you don't need to be so strict, and fewer functions require fewer resources-Sera, now!"
