Extra TiC I'll consider for the next version, as I'm in the final testing stages of 0.0.6. Metallurgy adds a bit too much for my liking with the current state of the pack.add like Extra TiC and metarllugy
0.0.6 will be changing the levels you get random/extra modifiers a bit. It will also slightly decrease the xp needed for each level as well.I think it level up 2 or 3 times, but it dont got any modifires
Bonuses (extra modifiers / random modifiers) will alternate every few levels. Starting with Random, the lower levels will look like : 1, 3, 5, 7, 10, 15, etc.
