Actions taken with AV up to today, in order and by Turn:
- Turn 21: Investigate the constantly-dripping blood of the Wisdom's Asp.
- Turn 25: Investigate how living things react to exposure to the Vitae.
- Turn 26: Investigate the exact circumstances required to induce a transformation.
- Turn 27: Investigate how the Vitae reacts to Dwarven magic-dampening Runes.
- Turn 28: Attempt to interest a prominent and knowledgeable Runesmiths in the interaction between Runes and Vitae. (will start at the top and work your way down)
- Turn 36: Investigate how the Vitae reacts with Divine Magic.
- Turn 38: Investigate how the Vitae reacts to a power stone.
The two remaining actions thus far are "Investigate how the Vitae reacts to being subjected to power stone creation methods" which has been crossed out because we don't know said methods, and "Instead of seeking the secrets of the blood, simply see if it can be weaponized in some way.", which was an option from the very start but has not yet been chosen (I would assume because it's easier to weaponize something if you already understand all the other things it can do).
Mathilde only bought her Ulgu power stone by Turn 27, but the possibility of using a power stone was a crossed-out option after that first action was taken - Turn
22.
That said, TimEd is right, no way we/Mathilde would have had the willingness to experiment on this without the Room of Calamity.
