The trophies for beating it in a certain number of turns are just silly, they're too dependent on you getting combos that can only happen at the whim of the RNG...
There are simply too many types of blocks that can appear in such a small area for it to flow well. Too often you're stuck using 2-hit combos at best, and breaking through a single shield at a time at worst.
I think the problem with Baconater isn't so much that they're tough (though they are) but that the strategy to beat them is counter-intuitive towards the rest of the game- that is: focusing firepower, rather than trying to create the most damage. It ends up being a little excessively difficult because all your abilities are geared towards causing the most widespread destruction, not focused destruction.
@Apologize2L, I agree, I have no idea why 4-15 hasn't been fixed. The random nature of the card-drawing gives me turtles and poison wands as an army of cyclopes beats me to death T_T
Does the speed stat actually give you more turns or does it just determine turn order(in other words: is it useless?)? I've been dumping points into it and my character doesn't seem to go more often than anyone else.
DooM Ace is right, the slave stats shown before purchase are totally unrelated to the stats after purchase. Considering she has one weapon that doesn't augment stats I doubt gear is the issue.
