>>13864535I will answer you supposing the way explained here
>>13863216>hit Golurk with a Dark/Electric type moveBecause Ghost, it should receive 2x by Dark and 1x by Electric. Because Ground, it should receive 0x by Electric and 1x by Dark. Then, (2*1+0*1)/2= 1x. So, Golurk receive basic damage.
>hit a ground/water type with a grass/water type moveBecause ground, it should receive 2x by grass and 2x by water. Because water, it should receive 2x by grass and 1/2x by water. Then, (2x2+2/2)/2 = (4+1)/2 = 5/2 = 2,5x. So it receives 2,5x damage and it can be tied to "super effective".
>hit a rock/steel type with a fighting/normal type attackBecause rock, it should receive 2x by fighting and 1x by normal. Because steel, it should receive 2x by fighting and 1/2x by normal. Then, (2x1+2/2)/2 = (2+1)/2 = 3/2 = 1,5x. So it receives 1,5x damage and it can be tied to "basic damage" or "super effective".
