Hello,
Sigils of Hope is a great buff, but it completely breaks up the gameplay and impacts it in a negative way (For me at least).
I am suggesting Last Wish (6% chance on kill to summon a sigil) to be changed to: 6% chance on kill to Summon a Sigil, and 6% on hit against Rare or Unique Enemies to Summon a Sigil. There are a few skills in game that already have an interaction like this.
With this change, it will make it way less clunky to use, because having to use all your mana every 15 seconds to maintain the buff just flat out isn’t fun.
