Great trainer, however some feedback/bugs
Numpad 1-4 inclusive work just fine and are the most useful. (unlimited Health/Power, Fast Cooldown and unlimited potions)
Numpad 5, Megagold, too much gold, max allowed by the game is 999,999. I'd suggest reducing the amount to about 100K, which will probably be more than enough, but can always be used again if more funds needed.
Numpad 6,Ability Points worked fine, once I got the hang of it.
Numpad 7, Player XP worked great, used to level my party to 15, then went into slaughter mode in the Hinterlands
Numpad 8, Mega Crafting Items, really buggy, first 99 items is too many, I would suggest 25 or 50, also even when this feature hasn't been activated, selling surplus crating items to a vendor results in me getting to gold for the sale, PLUS another stack of 99 items. Destroying 99 crafting items, also just gives me another stack of 99. Some crafting items, such as Wisps, not sure what they are used for as they have no description, are also update to 99, but appear in the inventory in multiple stacks of 3. I'm having to kill the trainer and the game, restating the game without the trainer running to sell/destroy crafting items.
Numpad 9, Super Gold Sale, not needed, use for something else perhaps.
Numpad 0 Inq. Power. Not used, with 1-4 activated, getting power from quests etc, hasn't been a problem.
Numpad /, Unlimted Focus and Numpad *, Unlimited Inventory, not found a use for these yet, maybe useful later.
Hope you find this helpful.
