thank you kindly for your attention to my query about splash damage. The problem is likely a result of my ignorance of the expected weapon performance in a variety of battle formats. Please accept my humble apology for creating a problem where there was none. Splash damage was a result of the alteration status in a particular battle. Still not happy about introducing splash damage to twins, however, I now know the reason for the damage I thought would be alleviated by the purchase of the alterations.
