Drop from Brumal Slither in Adonis Abyss.

anybody knows droprate?

Ehm....where can this slither be found?

Adonis Abyss. lol

Rubbish.. a 200 stamina chest gives 55 points and has less ability requirements. HP and AC are also in "normal" symbiants of that req range...

not that rubbish. 500HP & 50 Stamina - interesting option for pre103 enf-twinks. Sta is good for keeping some phat armor non-OEd (like ... T1/2 or Penultimate). One'd lose 28 BM/MM and 19 2HB comparing it to Vibrating Infantry Chest. So my guess it's best for NR not 2HB enfos.

Others may still consider it as it gives 100 HP more than Vibrating Chest and adds 50 Sta.

Infantry chest symbiants also include body development however. So while this symbiant adds 500 HP, and a QL200 Growing Chest Symbiant, Infantry Unit Aban only has 401, the Infantry symbiant also has 101 body development which becomes an additional 202-404 HP depending on breed. Therefore, this custom symbiant has somewhat limited usage in my opinion, considering what other mods you would miss (nanoskills, dimach).
