* **Heavy Slam** – High-damage melee attack at close range.&lt;br /&gt;
&lt;br /&gt;

* Resistant to [[Slash Damage]]&lt;br /&gt;
* Weak to [[Blunt Damage]]&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
== 🛠 Strategy Tips ==&lt;br /&gt;
* Always use [[Poison Resistance Mead]] before the fight.&lt;br /&gt;
* Use an [[Iron Mace]] for optimal blunt damage.&lt;br /&gt;
* Clear summoned adds quickly to prevent being overwhelmed.&lt;br /&gt;
* Fight during the day to reduce additional [[Wraith]] spawns.&lt;br /&gt;
* Consider building raised ground platforms to avoid constant water debuffs.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
== 🔥 Forsaken Power ==&lt;br /&gt;
