>>280742386 (OP)At first in part three they had to test in order to understand the ability, or either training the stand to get one.
For this reason most of the stands had basic powers like Emerald Splash or cut harder.
Even jotaro and Dio had to test their own powers first to understand the world/star platinum could stop time.
Heck even koichi had to find out the abilities od Echos the hard way since Act 1 against the Locket midget.
Or even Trish with Spice girl teaching her during battle.
