Exploit: Weapon Swap with Scepters allows for Companion without Spirit Reservation

Exploit: Weapon Swap with Scepters allows for Companion without Spirit Reservation.

Reproduction steps:
1. Have Scepter in one of your weapon sets and not the other.
2. Enable spirit reservations to reserve enough of your spirit so the spirit from your Scepter is used, enabling a Companion as the final reservation.
3. Allow said companion to die (like with the infernal legion support)
4. While it's reviving, weapon swap off of the scepter.

Result: Your companion will then revive and fight with you on the non-scepter weapon set, allowing you to have a companion you didn't pay for.

Other details:
This was using two companions.
The companion being revived without paying for it was using Enormity support.
