Press desired hotkey. All hotkeys can be changed on the trainer.

Trainer Options:

Numpad 1: Massive Resources, Money, Practice Points

Numpad 2: Talent Skills In Combat Always Available

Numpad 3: Max Item Rarity Drop Boost

Numpad 4: Max Rare Chest Boost

Notes:

Numpad 1: Massive Resources, Money, Practice Points - toggle this on and if you already have a point, gold, or a resource, this will set it to a high value and also when you use that resource or point, then you permanently have that much.  If you didn't already have at least one of the item in your inventory (gold for instance) then it will only appear that you have more.  This essentially lets you craft anything if you have at least one of the resources required, as well as upgrade your units infinitely to make them super units.

Numpad 2: Talent Skills In Combat Always Available - while in combat, toggle this on and your talents are always ready to use if they are not in cooldown.

Numpad 3: Max Item Rarity Drop Boost - toggle this on at the town and then when you go into combat, at the end you have a better chance for amazing items.

Numpad 4: Max Rare Chest Boost - toggle this on at the town and then when you go into combat, at the end you have a better chance for amazing items.
