I have to say the drop rate of legendary monsters is so low that maybe most people can get only 1 legendary out of 20 eggs even in festivals.
We have a online chatting group that consists of people who love to play this game. Exactly everyday I can see lots of members in the group complain about how unlucky they were when rolling for eggs.
And it makes people even more frustrated if legendary potion is same hard to get.
I suggest that Tower events including both normal and ultimate versions have rewards of at least one legendary potion for top 50 or 100 players or more.
finished 24… did not bother after beating the 3rd gatekeeper figured it would be sufficient for top 50… I agree tho top 10 is stupidly limited for legend potions.
only viable way I have now is to do the dungeon challenge n reach floor 80
