I've encountered a few situations where Combat Skill makes strange things appear on a character.
When using Batman in one mod, it put a cross or plus symbol over his head, which went w/ him everywhere he went. Same thing w/ Darth Maul. I reconfig'd my Thor the other day w/ Combat Skill as a new attribute & it made him have green bubbles flowing off of him & when the mission started, there was a notification of some kind that appeared over him, like he was hit w/ something that made him take damage, but it then said "BUOYANT". Very odd. It disappeared after some time in the mission. It was like something that would trail behind him when he ran or flew. When I removed Combat Skill as an attribute, the phenomenon went away.
Per investigation & the forums, the only way to make these things go away is remove the attribute.
Just wondered if there's something I have to combine with it/some way I need to use it to make it work & NOT display some kind of oddity. Stinks not being able to use one of the attributes. Gracias, amigos.
I have these same thing happen. You might try asking around in the scripting forum...
So, what you are seeing is the graphical indicator for increased damage. The same thing happens when MM uses his 300 Percenter. You MAY be able to adjust how the game displays that this is active by looking at the FFXEdit, but I'm not sure it is one of the customizable attributes. The bouyant thing I'm not sure about. That shouldn't have anything to do with the damage modification.
Some of the attributes trigger a weird humming noise when the characters spawns and also when the characters disappear after being defeated. I've inquired about it before, but I think I was told there was no fix.
