So, I'm quite a good player on Tap Titans 2, Heres some tips :
-Dont Spend To Much Time On Heroes, but pay attention still.
-Try look for the fairy's, they can boost you.
-I recommend prestiging asap, over and over, I found it very very usefull.
-Dont upgrade power ups unless you dont have anything else to spend coins on.
-Join a clan
-Try get a full item setup
-Upgrade the good relics
