Improved/Advanced Arm Guard 1

[Ryxingeir]

The npcs who craft the slotted arm guard, the improved arm guard, and who slot improved arm guards are all inside the ninja guild in Amatsu - however, if you don't have enough job levels they'll just tell you off (i think you need to be job 25-30, but i can't remember)

arm guard [1] = guard [1] + arm guard + 10-30k zeny
improved arm guard = mirror shield + arm guard + 20k zeny
improved arm guard [1] = improved arm guard + buckler [1] + 40k zeny (has a chance to fail to be made)

that's how their made, as far as i can remember - good luck ninjaing stuff *bows*
