At Chapter 9 towards the end, Will talks to his various companions and they all get a power up. Does this only happen for the girls (excluding the 3 heroines)? When you select a character...

the text says...
"A huge battle is about to break out... I need to talk to everybody that's going to be fighting with me."

Uya and Crayl etc... they all fight with him as well.

Unfortunately, yes.

Well they only get some new abilitys, nothing great.
And it changes nothing at how bad Aht and Suina are in comaprison to everyone else. (God even after reincarnation are still weaker than most without, thx to the worst stat increases ingame)

Suina and her Bowling Ball is enough to kill a boss, lol.

Early on it is, but eventually it becomes the same as other weapons and loses it's attraction. Suina just isn't as useful as other characters who have high-range skills imo...

Suina is still more useful than Wil.

Meh, I wouldn't say so. Wil was fairly well balanced and had a fairly large pool of HP thus making him a good tank and has a fairly large attack, plus he can exploit a lot of weaknesses w/ his fair variety of hammers.

Also, resurrecting old topics... no real need bro.

Well since it's here, why not: Wil is actually way more useful than suina.....Early on she's a bit more useful with her casting spells damage wise, but eventually will gets more HP than most characters, double action (giving him a high movement speed per turn) and his damage even gets higher, not only due to double action, but just as per damage per fight in general. Suina....well throughout the game she just remains the same....her damage just gets lower and lower in comparison as the enemies get tougher, her only advantage is against those weak to her element.

I concur about Suina. Wil's one of your strongest characters in fact I think the reason he doesn't get something like Prevail is because it would break the game.. then again there are other characters that do that anyway.

Edit: Oh and yea Wil's quite the sexist he really doesn't care about anything that isn't in his harem which is why he doesn't train with Crayl, Uya, etc.

Poor Crayl no bro love from Wil

are you somehow implying that aside wil there is a male character in the game worth wasting time with
