Walk behind your enemy while hiding. All detecting skills will not be able to detect a Stalker in this mode. The stalker can not attack and he will become visible when his SP runs out. Furthermore, attacks that impact the area that the stalker is in will end this skill thus revealing the stalker. The Stalker leaves faint shoeprints on the ground while using this skill. Walking speed is reduced, but this can be compensated with higher SkillLV. Can be used during Guild Siege, but costs 5 times as much SP. After a delay of 10 seconds, it will increase STR for 30 seconds.
When in PVP mode it has a chance to reduce all sword and dagger damage by half and returns the other half to the attacker for 3 hits. Works on monsters regardless of their weapon.
On player in PVP: Takes equipped weapon, shield, armor and helm off player and prevents a reequip of ANY weapon, shield, armor and helm for a certain time. On monster: reduces Attack by 10% and DEF by 30% for the skill's duration. Full Chemical Protection counters this skill. Success Chance is (5+2*SkillLV)%.
