I feel ya, i spent tons of training items to max out AGL Caulifla SA with teh STR Caulifla's. xD

You have Korin Tower and i "heard" that Quest 18-3 and http://dbz-dokkanbattle.wikia.com/wiki/Ultimate_Awakened_Power (stage 1 z-hard) both gives training items, but i can't confirm because i did not clear neither.
