Not really sure why you would take a spirit trinket anyways since you're trading int for spirit at a 1:1 ratio. If you want more spirit stack spirit gems and make sure its on all your gear. At least with gems you are trading int at a 2:1 ratio and on your gear you are trading other secondary stats for spirit also at a 1:1 ratio. You should be easily able to reach 9500+ spirit without even trying which is plenty. Int trinkets/flask/food ftw.
