Izroth's First Baneful Sword: Destruction completely obliterated the Undead Netherworld Skeletal Beast with a single blow!
The original HP of the skeletal beast was only 49,222. The reason it spiked up last time was due to the death of the Undead Netherworld Skeletons that was accompanying it. Therefore, Izroth's attack with the Two Solar Extremities Pill and some of his Essence infused into it was enough to take care of a level 40 elite monster like the skeletal beast.
Even though the skeletal beast did not have as much HP as the average elite monster that was around its level and its defensive capabilities were practically nonexistent, in the end, it was still an elite monster that should not be too looked down upon.
After all, how many players within RML could deal over 55,000 damage at this time even with the skeletal beast lacking defenses? Even if there were any others, then they could only be counted on one's fingers.
