Notes
- Use ends combat and X is the base XP for that foe plus 1/2 per FT added. This item ignores XP modifiers.
- Y is the same as X up to 250. The amount past 250 is given by the formula:
Y=250+ceiling[√X-250] - Using this item ends the combat, but doesn't always count as a victory:
- doesn't count as an adventure when exploring Astral Badlands during the relevant part of the quest;
- doesn't clear a sections of the clock caves in The Mouths of Darkness during the relevant part of the quest;
- doesn't add a victory in Sector 7-Gamma;
- does clear the rooms in NCI Live building;
- does clear another CTC foe when opening the mini-bosses during the relevant part of the quest;
