Fused Staff Feat 8
Source Pathfinder Impossible Magic
You can use your arcane prowess to fuse a magical staff into a weapon during your daily preparations or as a 10-minute activity with the manipulate trait. The fusion lasts until you fuse the staff again or the weapon is out of your possession for 24 hours. The fused item has the staff's activations and other benefits, and it can be used to cast spells if you prepare it. The staff and the weapon share their fundamental runes, using whichever weapon potency and whichever striking rune is higher level. If the staff has property runes, they're suppressed while it's fused.
The item's fused abilities work for you alone. A different wielder can use the weapon normally, but they don't get the benefit of the shared runes and can't use the staff's spells or abilities.
