That's not what is supposed to happen though.
As you can see from this screencap, the Chain Max Targets is 4 for an un-upgraded Shock Therapy.
Click on the Green Upgrade button for 150 Mana and we see an increase of 400%...
Clicking on the "i" again we see the new Chain Max is "20" but I have not seen this to take effect!
Other people have, but I have not... will test and see if I can get an update on this for the people :P

I think is a display bug, I'm working on API and the idea I got is that you start with 4 max chains and then increase by 1 for each upgrade, and it would also make sense
these are 5 upgrades
level 1 = 150 mana for maxTargets and a value of 5
level 2 = a value of 6
I get what you are saying - but I am not that savvy to pull api data (dm in Discord if you want to share how I could pull that)
So I can only go off what the game tells me... as would every other player...
When the game states that the upgrade now has a max of 20... but does not in fact have a max of 20 lol... well you can see the issue :P
