On the build guide https://gwpvx.fandom.com/wiki/Build:Rt/any_Spirit_Spammer
it says for weapon:
Weapons
- Adept channeling magic staff of mastery with "Aptitude, not Attitude".
- Note: Weapon modifiers such as Halves casting time on spells of item's attribute (Chance: 20%) don't apply to signets and binding rituals as these skill types aren't subordinate to spells.
What's the best way of making/getting a weapon like this?
