Ede Saine

The Ede Saine is a unique small spider species that Kumoko evolves into. It is feared as the symbol of death. It has a very high combat ability and stealthy nature. Evolving into this species levels up Taboo. Its entire body is black, except for a white skull pattern on its back. Two of its front legs taper off into scythes.

A spider-type monster feared as an omen of death. It's said that the moment you encounter this terrifying creature, your fate is sealed. Because there are so few living witnesses, it is difficult to assess its precise danger level. It is estimated to be at least level B.

Trivia

 * Normal Zoa Ele and Ede Saine do not have the skill Rot Resistance. As such, using the Rot Attack skill would usually kill both the target and the monster. Kumoko's Rot Resistance was gained from eating an Elroe Gastruch of the Lower Stratum of the Great Elroe Labyrinth, and allowed her to not instantly die when using the attack.
 * Kumoko apparently loses the Dark Resistance skill she had as a Zoa Ele, only to regain it later as a Zana Horowa. This error is also present in the Japanese version.
