It´s really a shame how even a constructed enviroment like the Paladin challenge doesn´t make GG attractive. It´d be easier without GG (like anything else) but they outright force you to take him. It should be constructed in a way that the only way to beat the boss would be to get GGs best boon but instead it´s a demonstration of the ways GG screws you over.
He can cure me of afflictions? Well I´d be able to avoid them if taking them wasn´t how you get piety with him. He gives plenty +HP? Yeah if you sacrifice XP/levelups. He can heal and restore MP? Less than the potions I´m not allowed to drink!
Sigh, yeah I´m ranting but I really expected the bronze challenge to be an effort in demonstrating GGs good points. But even (or rather especially due to the lack of conversion) with the "Religion-abuse" class he isn´t a good choice.
