Gonna be frank, this trainer doesn't work that well. Stuff is labelled wrong, unlimited armor is health (there isn't even armor in this game). Unlimited health is mana instead.
Unlimited Armor (Health) affects enemies as well making the feature pretty useless, as the battle will simply never end.
Unlimited Health (Mana) Seems to be working properly.
Unlimited Gold also seems to be working.
So in short this trainer could use a little bit of polish.
Probably has something to do with the June update that came out after trainer, if you haven't already make sure you put in that update request so it gets looked at.
