Does anyone know exactly how much damage Fractured adds to a weapon? Is it straight damage or a percent?
EDIT:
Did some science, found out a few things.
1. Fractured damage is included in the damage shown in the tooltip
2. Fractured adds a fixed amount of damage, but that amount is different for every weapon type:
Cleaver: 1.8 dmg
Broadsword: 1.5 dmg
Longsword: 1.65 dmg
Scythe: 1.13 dmg
Rapier: 0.83 dmg
Either Minecraft or Tinkers seems to round the damage to 2 decimal places, considering the weird numbers like 1.13 and 0.83.
EDIT 2:
Took a look at Tinkers' source code, found out more stuff.
Tinkers tools actually have 2 attack stats - the one that you can see and Minecraft uses to deal damage, and one that's used internally by Tinkers. Quartz, Fractured, etc. influence the internal attack stat. This internal attack stat is multiplied by the weapon type's "damage potential" value to get the attack stat you see (the one that actually influences how much damage is dealt out). This results in Fractured effectively adding 1.5 damage to the tool head's base damage.
