Hello dear community I would like to shortly tell you about adding to the server Iguana Tweaks for tinkers construct mod. This mod adds ability to level up tools and ables to change parts in it. Its some kind of addon to the TiC Code: http://bit.ly/1zsbRFB
Would require it on client side too, so no as we want to keep the server compatible with FTB Launcher
Iguana tweaks is a mod. We can not add any extra mods to the server. You will need to suggest it to the Pack creators from FTB.
although i agree it would be a nice addition to the pack you should go and make a post on the ftb fourm
