Apprentice II
When using runic reforging and an Oak runic tool having the following properties selected: "Grand Artifice" and "Inspired Artifice" and selecting Vicious / of Slaughter there should be only 1 to 2 properties rolled. You should mainly roll only HCI with a chance to roll a second mod. I've used 81 charges of Oak runic tools and I consistently get results like so:

Out of 27 attempts I've received HCI as the only mod 6 of those times.
I've received 3+ mods at least 4 in 27 times as well (didn't put them all under a microscope to see which received resists as a mod).
These tools should only have a property range of 1 to 2 mods in the first place, so rolling 3 is definitely an undesirable result when trying to minimize the mods received.
Ontop of that the chance to receive JUST hci seems to be under 25%, which again is an undesirable result.
Examples of extra stat items:
HCI + Casting focus + Energy resist
HCI + Mana Inc + Casting Focus
