Hi. I'd like to know what you think of a mechanic I have been implementing in a game I am developing. It is a fairly huge game, and it is possible to find optional secret characters for your party. One such character is a sorceress that has, maybe, four or five spells, tops, but boy do they hit hard (her spells only target one enemy at a time). Every single one of her spell costs 99 MP (character may get a max capacity of 400 or so MP tops). I tested this optional character against a boss that was weak against Fire. He has a total of 18,000 HP, and her fire spell deal 23,752 damage. Ouch. Killed that boss in one shot.
Her other stats are fairly mediocre and even subpar. When other party members have like 1,500 HP she has like... 800. Also, later bosses cannot be really one shotted because they tend to consist of multiple waves or forms.
Cheap character? Strategic asset?
