Both of the above hacks are working for me. I've found a way to get unlimited portal stones / gold but I'm unable to post it as a hack because I don't have enough posts :(

EDIT: Posted a few times and submitted the hack

Assuming you started with 10 stones, you need to do the following

-Scan for 10
-Throw one stone in, click through hero screen
-Scan for 9
-Repeat until you get 1-3 addresses

If you do it right you'll get a few addresses and if you freeze them first, then change value to the same, it should work. It only levels up Fighter, so I got him to 7 stars. I put on an autoclicker to automate the gold collection and after a while I had about 1 mil gold. I've done this hack several times now. If you don't have a bunch of stones just scan for 0, then when you get 1 stone scan 1. Repeat as you gradually get stones and eventually you'll have narrowed the search down enough to try it. It works best if you're already at the stone screen before you change values, but once you have the addresses you can change and freeze the values and it will trigger the portal screen.

All the hacks posted work. Trying to find more... :/

Same can be done with Catacombs Score :P (Two addresses, just track them while gathering points)
Your server side rankings won't be saved, however you will be able to collect all the rewards

It's not weird, for some reason throwing an empty stone gives you an unidentified hero, then the game defaults to Fighter. And yes, same with gold stones :)

Thanks for the hack Filigestii.  Neither of the things he linked are shoddy or suspicious and he offered a genuine solution for someone wanting to hack. 

Thanks for the hacks guys! Btw catacombs score is caried into global rankings if you complete one battle legit way. Also havent you found way to cheat training points/skill points or guild marks? Thanks for reply!

Am I the only one who gets crashes with the stones hack?
I have no trouble narrowing down the address for the stones. I've tried the hack with the stones pack from the guild shop and it worked wonders.
It's the 4th time I try it with the number of stones at 1 (instead of 4 or 3) and it crashes the game. I'm currently waiting for the stones pack but my guild takes four days to gather 20k guild marks.
