Well, not sure if intended or not. But if you use the force upgrade option. You can upgrade charge units indefinitely. Inquisitor + Sand of Time or w/e the row charger is called can still make a full infinite loop. You put Core - Sand - Inquisitor and upgrade Inquisitor's charge to 3.5s and Sand to whatever CD you've used "improve damage" to reduce inquisitor to. They then full infinite and also infinite the core (or whatever your third unit on that row is) Ideally the growth core or the charge column core if you need two more infinite units for...something. Then you could put that regen charge right unit on that row to spread it even further, I guess? But at least you really have to work for your charge engine now. You don't just get whole infinite board for free by like turn 5-8.
Mirror of Eternity or w/e the +10 Top shield unit is called is also pretty much an auto-include in anything that isn't using +x*. Since you can just upgrade that infinitely. I think +120 is the highest I've had it. But that was last patch, this patch you need too many upgrades elsewhere (charge). I think just by design the "Any" triggers are way too strong. Same goes for the regen tree dude with +1* on Any. Even with me using it to share power to my poison unit every time I got the option. It still ended up around 15-20k regen.
The share power thing is completely broken currently. It drops the power of the unit you use it on to 0 and give seemingly 50% of the base value of the unit you use it on to the other two. I used it on a 500-something unit and it gave +7 to the other two units and set itself to 0. The other one, where one unit gains 25% of the other two units on the row still works as intended though.
Edit: Made it to 47. Every single loss was to poison counters one-tapping me with no counterplay. The crit interaction is so OP though. I had the Any +x crit regen dude with +45 crit to 9 random allies. So my Inquisitor was infinite hitting for around half a million per hit (which still can't get you to level 50). I also had several millions of shield and Regen ticks in the 50k range. Doesn't matter though since 19k base poison being applied to you via reactions will just instantly kill you. The weird thing is when your enemy has poison < regen their damage from poison doesn't show up in the after fight report. But it does still move your health bar and can still kill you.
Edit2: If you use something like "improve heal" +10% crit. Then gain +crit during combat. The +10% "permanent" crit gets deleted at the end of that combat. Also got to Wave 51, scaling around 50 gets completely cursed. Base values go from like 20k to 220k in I think like a few waves. I had a 98k poison reactor one-tap me. Then at level 51 a Shadow Assassin with 260% crit chance clapped me for over half a million about 1s into the fight. Even my obscene amounts of shielding can't deal with that.
