You see, what I do sometimes is I'll open a tab on my laptop and use the Google calculator function to figure it out. Say I'm going to use a Colossal Ra with 3 blades and 1 trap with various values, I'll Google this:
875 (the average Colossal Ra damage) *1.69 (my character's damage) *1.25 (Balanceblade) *1.3 (IC blade) *1.35 (Enchanted blade) *1.3 (Hex). Then Google tells me the answer. I have to do it rather quickly, but can definitely do it myself in a turn, to find out whether or not the spell will kill. It might make the game a little easier if this was added, but it's not very needed.
Timers are necessary for team play. Calculating should be done outside of combat. You can make the small calculations of changes from shields or charms on the fly. If you already know how much your spell does with X number of boosts, it's a simple calculation.
I think something like this would be an excellent addition to the game. Right now I use the calculator on my phone to see whether or not a hit will kill an enemy. The buff list that was added not long ago was a great step in a similar direction ... perhaps they'll capitalize on it someday!
Once a super fan, now a KingsIsle QA Tester! I squash bugs.
I wouldn't be opposed to the buff list showing a total buff, but anything actually calculating the total damage before hitting is just stupid in my opinion. It makes battle kinda pointless. Let's just give tests with all the answers printed on it for you too. Just circle the only answer given and you win. At least the way it is kids might actually THINK and do a little math. The game doesn't need to do everything for you.
