currently doing an elf cleric wisdom based ranger was thinking FVS/Rogue Splash for solo trapping but might work more toward a set armor for evasion needs when trapping. as well maybe key lock ring and some skill points in disable/search human get an extra DC feat for casting maybe. I've done it with 1 level rogue but it was ranger who got evasion later. probably 2 levels rogue. I try and craft my spell schools into my equipment and augment ability enhancements up to level 20 .
