I just wanted to make a powerful long bow with tetra using my icedragonsteel ingots from iceandfire mod today.But I realized that it needs 9 tier hammer available to make it. I am using tetra's underground hammer with 2 tier upgrade modules but it only gives me 7 tier.So,how can I possibly get 9 tier? I've tried to look config file and edit the requirement values but I couldn't even find config file of tetranomicon. help me pls
