FFVI Worlds Collide

Scaling with the highest level party member will increase the difficulty while also making it easier to level a lower party member in a team of higher level characters.

A friend of mine found that they were blasting things with Stone from Brawler Rage(and later, Gogo and Strago could learn it by being in the same battle). Scaling with highest level party member may even make this easier on average, because just giving those three a couple levels over the rest allows them to take advantage of the 8x damage from being the same level rather easily. Not sure how to go about this other than just leaving it in, but perhaps it would be possible to have the scaling randomly pick one level above or one level below, reducing Stone to only having a 1/3 chance of being very powerful.

Did you have the Vanish/Doom bugfix on? I also modified this battle's AI so it is possible there is a bug in the script. I will test this out again when I get a chance. Thank you.

Vanish/Doom bugfix doesn't fix the WrexSoul battle because the SoulSavers are naturally vulnerable to Instant Death.
