Is there a way to nullify this verb until you speak to a certain mob and if your PL is great enough, he un-nullifies it for you?
Here is the verb:

mob/pc/goku/verb
SSJ()
set category = "Forms"
if(usr.ssj >= 2)
usr << "You cannot Transform Into A Lower level Than You Are Already In!"
if(usr.maxPL < 150000)
usr << "PowerLevel of 150000 Needed for Super Saiyajin!"
if(usr.ssj == 1)
usr << "You Are Already in the Super Saiyajin State"
if(usr.ssj <= 0)
if(usr.maxPL >= 150000)
flick("ssj",usr)
usr.icon = 'gokussj.dmi'
usr.maxPL *= 10
usr.str *= 10
usr.def *= 10
usr.ssj = 1</150000>
