Neat laddy, here are some tips: depending on how strong you want it to look, like if its strong, a smol sinkhole will appear with small rocks going around, now if it's super strong the screen should shake while following strong, now for S T R O N K, make the springing look concentrated and suddenly a few swipes of line will appear with some smoke and big chunks of rock flying and stuck to the sinkhole, maybe even shake the screen too( I hoped this helped. God bless ye and Godspeed)
