Combine the 803.805 gem with 2 other gems to create a total value of 997.599 - 999.999. The ritual bonus will make it 999.999. Create 2 more of these gems and combine all 3 of them to create a perfect gem (2.999.997).
That wouldn't solve the problem, because you can get health back multiple times during the raid (definitely when you have it at 25%). So some people could still get 2-stars after 7-deaths with lvl 40 traps.
So, many people (including me) are complaining about the heartbeat upgrade. Now anyone can get 2-stars after 7-deaths even when all traps are 26+.
This is way too unfair because many bases have designs that are good after 7-death + DT if the thief gets 1-star. However, with the heartbeat upgrade many bases are destroyed due to heartbeat giving 2-stars after 7-deaths with traps lvl 26+, so right now upgrading traps to lvl 26+ is almost useless.
If this won't be changed, no one will run big gems except in a good platform or gravity base.
Right now most of the people have heartbeat around 7% and once everyone reaches max (25%) they will get health back at least once per
raid almost every time.
There are a few great ideas to balance this:
The simplest way (IMO) would be just removing the whole upgrade and giving back all the tears you've spent on it, but I'm sure this won't happen.
I've seen this idea a few times and I think it's the best one. The idea is basically increasing the 7-death rule each time the heartbeat activates. This would balance the game and make 7-death = 1-star a thing again. It would also make more people do big rituals, which helps us find more big gems.
This upgrade needs to get balanced ASAP and Zeptolab needs to start working on it right now!
