Talk:Mighty Shout (skill)

MP cost

The more turns you have of the Mighty Shout (effect) (let's call that t), the higher the MP cost to cast it again.

The first one costs 15 MP, and then each cast cost this more MP than the previous cast:

15+30t

So the cost to cast this, if you currently have t turns of the effect, is:

15(t+1)+30(1+2+...+t) = 15(t+1)+15t(t+1) = 15(t+1)²

And the cumulative cost to get t turns of the effect is:

15(1²+2²+...+t²) = 15t(t+1)(2t+1)/6 = 5t(t+1)(2t+1)/2 = 5(2t³+3t²+t)/2 . --Pcentella 16:39, 28 June 2009 (UTC)

The info on this page is incorrect. The MP cost starts at 15 each combat and goes up according to the formula based on the times it has been used in the current combat. I entered combat with 4 turns of the effect active and it only cost 15 to cast, and then 60, etc. --CheezyBob 05:30, 2 November 2010 (UTC)

• Agreed; I started several combats with varying numbers of turns of Mighty Shout (worked up to 5 turns at the combat start) and it was always the same cost: 15, then 60, then 135... I'll reword the page. --Terion (talk) 21:23, 17 March 2013 (UTC)
