Effect: 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.
