In this case, I'm introducing a couple of magical pieces of leather armor. Perfect for your thief or multi-classer who wants his own magic armor and is sick and tired of "+1 Leather."
Spider Armor: This bright maroon leather is +1 leather armor, but grants the wearer +3 on all saves vs. poison, allows the wearer to climb walls like a thief of the same level, and reduces falling damage by 50%. If a Thief wears this armor, his Climb Walls increases by 3 levels of experience. XP: 800.
Leather Armor, Displacer: This is +1 leather armor, but for 6 rounds per day it can cause the wearer to become “displaced.” When displaced, the wearer appears to be 3’ (ahead, behind, left, right) his actual position. All attacks against him are at -2 to hit. Additionally, the wearer receives +2 on all saves when displaced. XP: 1000.
