Can you improve the function, so that the damage is caused by bolts needn't to be dividable by three? Maybe some rounding?
Otherwise is a great tool for my lazy days, when I have no desire to use mental arithmetic. 8)
Ugh.. It looks like somebody messed up with the formulas. -.-
I'm assuming that you are referring to the "minimum quanta calculator" (the 1st one).
To answer you question, it already has rounding function and the division depends on the spell damage that you enter in the "spell cost". When changing the spell cost to 2, it will work for ice bolt and drain life. In fact, this will work if in the future we have a card where it will inflict let's say 4 damage per 10 quanta as long as the mechanic is the same with the current bolt spells.
I've fixed the formulas and it should work as intended. googledoc don't have function to protect cells. Again, just a reminder - only cells in yellow should be changed.
