Okay, I am a maxed engineer. As such I can make ammunition. I am willing to make Mammoth Cutters or Saronite Arrows for free for any guild member that can provide the mats.

Currently I require for Mammoth Cutters:
1 bar of saronite (or 2 saronite ore), 1 crystallized water, 3 bars of cobalt (or 3 cobalt ore). Or you can substitute 1 Volatile Blast Trigger for the crystallized water and the cobalt.

For Saronite Razorheads:
2 bars of saronite (or 4 saronite ore)

Simply mail Tyerol the mats in game with what kind of ammo you want and I will have it shipped back to you inside of 24 hours. While tips are appreciated they are in no way necessary as this is a service I am offering to my fellow guildies.

Edit: I should mention that the above mats create 1000 shots or 1 full stack in an ammo pouch/quiver.
