Summon Link: Summon
Summon Cost: 20 Energy
Currently, the link to summon the Giant Arachnid only appears on iPhone or iPod Touch. Everyone else can use the link above. After it is summoned, anyone can attack.
Your stats only helps to determine if you'll win or not your duels, like in a conventional guild battle. Damage/Stamina ratio is the same for everyone regardless of stats, and the only damage modifier applied is due to the Rogue ability (+100/stamina), Deianira (+20/stamina) or Deshara (+40/stamina if rogue as class).
