This patch adds a bunch of new abilities!
[list]
[*] Allegiance
[*] Exodus
[*] Flesh and Blood
[*] Hellfire
[*] Holy Hand Grenade
[*] Reflector
[*] Temptation
[/list]
I'll leave what they do up to you to find out!
I've also shuffled around a few upgrade costs and added cooldown as a reward to all active abilities.
