The Ranger lays traps and environmentally based illusions to upset and discombobulate the foe into various problems or even damage/death. The traps are laid only after being CAMO'd and once they are laid, the Ranger will lose the AS/HIDE bonus and return from hiding to cast again or do what else. Once the traps are laid, the foes in the room may trigger them without realizing it (as well as non joined characters). The effects of the traps will specifically build on the successful ambushes and kills of the Ranger so that the next foe in line for the Ranger's wrath will be hopefully hindered or already close to dead. For example, the Ranger has laid the traps and re-Camo'd (which gives an additional +5 with this 100th level spell running due to the illusions adding advantage). The Ranger slices through the neck artery of the first Ithzir seer and the body springs a trap which blasts into the next Ithzir they were lookin at. There's 5 more critters in the room and another 2 just got here. One of them springs a trap and gets chewed up by the snakes which came out of what appeared to be a mossy log, then they fell on another foe who collapses stunned. The Ranger re-Camo's and hits another Ithzir who dies and releases an incendiary which goes off and makes flames on several of the critters. One of them attempts to roll around and sets off an illusionary trap which gives the Ranger a bigger advantage in their next ambush, and so on...
