Int affects Mana Consumption and Casting Time

Casting times

I recorded myself casting some fireballs (same ones from below), got exact time values from the videos, and just averaged the casting times at different int.

• 1500 int took 15.33 seconds to cast fireballs on average.
• 1023 int took 16.98 seconds to cast fireballs on average.
• 0 int took 21.07 seconds to cast fireballs on average.

MP Costs

No mp reduction gear, no meditation, r1 fire mastery, r1 fireball, standard fire wand with no upgrades. Any time I noticed a lag spike, I restarted the casting to get more accurate data.

1500 int

• 1st fireball, 1164 mp -> 1106 mp, day
  • 1164-1106 = 58 mp
• 2nd fireball, 1106 mp -> 1048 mp, day
  • 1106-1048 = 58 mp
• 3rd fireball, 1048 mp -> 990 mp, day
  • 1048-990 = 58 mp
• 4th fireball, 990 mp -> 932 mp, day
  • 990-932 = 58 mp
• 5th fireball, 932 mp -> 874 mp, day
  • 932-874 = 58 mp

1023 int

• 1st fireball, 973 mp -> 909 mp, night
  • 973-909 = 65 mp
• 2nd fireball, 918 mp -> 855 mp, night
  • 918-855 = 63 mp
• 3rd fireball, 867 mp -> 804 mp, night
  • 867-804 = 63 mp
• 4th fireball, 814 mp -> 751 mp, night
  • 814-751 = 63 mp
• 5th fireball, 767 mp -> 704 mp, night
  • 767-704 = 63 mp

0 int

• 1st fireball, 887 mp -> 823 mp, day
  • 887-823 = 64 mp
  • maybe i recorded the values wrong for this one?
• 2nd fireball, 818 mp -> 737 mp, day
  • 818-737 = 81 mp
• 3rd fireball, 722 mp -> 641 mp, day
  • 722-641 = 81 mp
• 4th fireball, 570 mp -> 489 mp, day
  • 570-489 = 81 mp
• 5th fireball, 490 mp -> 409 mp, day
  • 490-409 = 81 mp

Conclusion

I believe I have successfully verified both that the base cost of fireball is about 20 mp for humans despite needing at least 25 mp to cast one charge and that intelligence contributes to reducing casting times and mp costs. Please let me know if more testing is requested.

A bit off-topic but how the hell do you have both 0 and 1500 Int?
