Designed a Keyblade for a character based on my Destiny2 Hunter, and therefore based the keyblade around Destiny 2 Supers and weaponry. Unfortunately there wasn't actually a whole lot of design process because I sort of just sat down and drew all this, and the elemental forms were all done with heavy experimenting on top of the original design, and I did not often save in-between iterations and experimentation.
Not included at this time is a Stasis-themed keyblade, as Beyond Light has not officially been released. Once it has been released I might design one for fun. As it is, these were designed for an art group and I was limited to three magic/element types, so the currently existing energy types in Destiny fit my purposes quite well.
