As title indicates, during boss encounters I will switch to spriggan form and my character will look like how he should in human form.
I will also have totems that will go invisible during boss encounters, such as with Lagon and during the winter druid boss encounter with the ice totem boss that duplicates into multiple forms of itself.
Edit: Also Lagon’s tentacles during the 2nd phase became invisible and so were my totems, so I had to run around like a headless chicken hoping to not get hit by invisible tentacles/waves and was rewarded with not being able to interact with Lagon at the end of the boss fight despite beating him.
