Thralls are indistinguishable from Weak Thralls, thus the only way to tell them apart is by checking their names. These Thralls are only found inside of Tower of Abuse.
They have near twice the amount of combat stats when compared to Weak Thralls, So caution is advised since there are around 5 or more in the Tower of Abuse.
The Statistics here are taken from FCS. Skills will be multiplied by the racial multiplier. Players should also be aware that non-player characters also level up while fighting.
Lore[]
It is highly inferred from several sources including dialogue with Cat-Lon that thralls are either jury-rigged or lobotomized skeletons. The former theory can be gathered from the skeleton shredders within the tower of abuse and the latter can be gleamed from Cat-Lon's speech before initiating combat.
Trivia[]
While most of Skeletons possess the sturdy 200 HP body model, Thralls are among the few models that have 120HPs. Since all of the Thralls use the 120 HP model and veryfew other models that use the 150HP model body, it can be assumed that the weaker, perhaps service-oriented or creative-minded, skeleton models where enthralled en-masse by their stronger 200HP cousins after the fall of the ancient empires.
