Ranger spirits not affected by boon duration
I can confirm
I have the exact same problem with spirits too.
Another thing I noticed was that the boons from nature’s vengeance only gets applied to one other ally. Also, each spirit’s boon can only affect one ally at a time. For example, I get all the boons from each spirit, all at once, but my allies each get only one boon from however many spirits I have up. I’m not if that’s how the boons are originally intended to function but I figured each spirit would spread their boons to up to 5 targets like their original non traited buffs.
There were also some cases where I get no buffs at all and it only gives it to one of my allies and ALL of these examples I stated were when we were right next to them and were in range of receiving their buffs.
