The raids will happen near Svargrond, Liberty Bay and Port Hope.
The Monsters which spawns are GS-alike, Demon- alike, Dragon- alike and Clay guardian alike. They look similar and have HP same as original monsters but their attack EXP is lowered. The damage received is mainly Physical, Fire & Poison.
They actually can damage (low) each other it seems:
17:29 An unexpected loses 3 hitpoints due to an attack by an unwanted. (suspecting poison)
The spawn of the raid will start every hour- last approximately 15 min (coming in waves).
|Unsolicited ||2625 EXP|| Runs on low HP|
|Unexpected ||2700 EXP||Summons Fire Elemental, Heals himself|
|Unwanted ||2580 EXP||Summons Spiders|
|Uninvited ||3000 EXP|
