I was just try to use this formular for pure terra level 30. no star and skill Sand Storm. when i use skill Sand Storm attact Flame elements, i see about ~ 8000. it wasn't ~11000 as calculation.
 * a = " 300 Base Power Dragon" + (" 600 Base Power Attack" ) = 900
 * b = (a + a*0.2*" 30 Level Dragon")*1.8   = 11340
 * c = b*(1+(0.05*"Amount Stars Dragon")) =11340
 * d = c*"Element Bonus =11340.

What is wrong at here ?
