Actually Angel Wing is in my point of view a waste since most of the time Rinoa uses status magic which is completely useless against bosses, and yes the power of her magic multiplies by five but considering she rarely uses powerfull magic atacks such as Ultima, Holy, Flare and Meteor it becomes useless and itīs quite annoying also, she doesnīt heal and she canīt do anything else besides using types of magic that rarely deal a lot of damage.

As for the card quest it also happened to me i had all the rules and lost almost everytime but i walked from town to town and eventually was able to catch all of the cards and use them as items.

And Wendigos arenīt really very powerfull just give them a good summon and they will die easily. You can also blind them and use the mug command to steal steel pipes from them.
