Chadwick and Tom’s Challenge - Not Worth the Effort
I used a 5/1 and four 4/3 champions, and only fought until chapter 1 round 3 before I realized the rewards are not worth the effort.
The recommended team level for Ch.1/Rd.3 was 5,500. My team was level 11,880 and I followed the easiest route, which was route A.
With the amount of potions and boosts I used (and I am soooo very frugal with using those things because I don’t like undertaking challenges wherein I have to significantly use them), the completion rewards were not worth it all!
Just my opinion :-)
