Isolde, a hero who has achieved great feats in countless arenas, was once known as an "invincible" existence. Today, I will introduce Isolde from the game Underground Castle 4. One day, an evil god rose from beneath the earth, bringing with it a vast army, intending to erode the entire world. It was this disaster that finally made Isolde draw his sword again. All these changes also transformed him into a new warrior, ready to face even stronger enemies.

Isolde's skill set is quite unique, allowing him to fully leverage his advantages on the battlefield. His basic attack, "Chaos Slash," deals physical damage to enemies within two squares in front of him and adds 2 layers of Dark Pulse. When Dark Pulse accumulates to 15 layers, it deals 30% of the target's maximum health as damage, greatly enhancing his damage output.

His energy skill, "Thunder Lance," specifically targets the enemy unit with the lowest health. The thrown thunder lance not only causes magic damage but also inflicts a paralysis effect, reducing the enemy's attack speed for 4 seconds. This skill is particularly effective when killing weak enemies, quickly weakening the overall combat power of the enemy team.

Isolde's passive skills also provide him with powerful survival and damage output support. The first passive skill, "Insight," allows Isolde to increase his resistance to ranged attacks by 70% and gain additional energy regeneration when there are no enemies around him. This makes him more durable on the battlefield when not being approached by enemies. The second passive skill, "Stability," grants Isolde a stable state at the start of the battle, allowing him to resist two control effects, enhancing his ability to withstand enemy control skills.

In terms of team composition, Isolde's strengths often rely on the support of his teammates. Since his skill design favors keeping distance from enemies or achieving maximum output when no enemies are near, the team needs a frontline tank to absorb damage. Additionally, since Isolde does not have self-healing abilities, having a healing character is crucial. For example, the combination of Fiona and the Dawnlight Priest will provide Isolde with ample survivability, allowing him to fully unleash his combat potential.

Isolde is not a character who solely relies on strength; his playstyle emphasizes precise positioning and the reasonable use of skills. When facing powerful enemies like Inquisitors, he not only needs strong damage output but must also maintain good survivability. Choosing the right tactics and team composition will directly determine whether he can achieve final victory on the battlefield.

This concludes the introduction to Isolde from Underground Castle 4. Isolde's design and background not only provide players with a rich storyline experience but also bring significant challenges to battle strategies. For players who enjoy high operational and strategic gameplay, he is a character worth delving into deeply.
