I may know the reason for Rika being less sturdy than Chaz when going up against those Witches. Actually, it applies to pretty much every boss that uses magic or techniques. Compare their Mental scores. I'm sure that by now, any fan would know that the user's Mental stat influences their ability for tech casting as well as the Magic Defense, which is in the game, but is hidden, but it also determines how well they resist magi/tech damage.
In fact Rika has one of the lowest Mental stats in the game, excluding Demi and Wren of course. She doesn't even max it out to 99, but rather,
89. Even Gryz manages to get his stat up to 99 when fully leveled.
This little chart my help you if you aiming for the really high levels, MrRoivas. It only lists the chars HP and TP.
Lvl 90 PSIV stat comparison.
Name HP TP
sorry about the code.
Hope it helps in some way. Thought I don't think it will be necessary to take them
that high.
Did I read correctly, Kaloes? You're soloing the game with Alys and taking her all the way up to PDarky?!?! Man, I admire your effort. That is going to be one tough nut to crack.
Just for reference, here are her lvl 99 stats. You may have to take her all the way up, and her stats are pretty darn good.
Alys HP: 646 TP: 476
All stats 99.
