[quote=@TheUnknowable] ok. I'll say it's moderate difficulty (15), since it's a complex part but an old design, so it's not as complex as the newer droids. Also, your are combining two damaged ones into one working one. I actually rolled 3-4-5-6 (weird), so that's 18. A success. [/quote] You have my thanks. [@Galgarion] Well I'm not exactly a tech expert but I would like to elaborate my viewpoint so that you can add more effectively to it and maybe help in sorting this out. I'm plating two cores in one droid, the second sitting in a lower center of gravity so as not to effect it's rolling mechanism. Secondly, this core will take on all the ability to handle the shields so as to free the load the on two more lasers on the primary core. Now for mounting two lasers on the back. They are much like the same Mantis type design as the originals, as in they swivel into place and are not stationery. They'll follow a more exaggerated path than the front lasers and will be mounted a bit higher so as to not disturb the original movement cavity for operation. I hope I can pull that of in a weird science way. If not, I'll just keep it as a pet project and try and modify the original design more heavily. What I am aiming is a more General Grievous kinda design from the droid. I think that would make it a beautiful threat to the enemies of Siador and maybe prove the worthiness of Miavenna which seems to be shadowed by Kilgaris at the moment.
