Sorcery Ward - Witch Hunter Ascendancy Obsessive Rituals

This thing is reserving 45 spirit when it is not indicated? This buff could have been just a simple skill gem if it's going to reserve spirit intended for other heralds instead. This passive buff skill like any other should come passively free like the hellhound without any requirements.It is basically taking away some slots from equips for other affixes just to have additional spirit for heralds.
