Rounded down to the nearest whole number
For boss duration, some bonus turns effects (the 'B' part of the formula) do not work:
- Time Wizard's talent : apparently works
- Bodhi Buddha Beads's +1: doesn't work (but the +30% part does work)
- Legendary Mage +1/2/3 rounds: ?
OR, possibly, bonus turns ('B' in the formula) for boss levels are summed, divided by 2 and rounded up.
