her iceblock can stand vs drogoz's ultimate when drogoz hit you in iceblock with his ultimate, even after iceblock duration you are immortal vs his punch
If you can land a Pyre Strike on Talus when he's approaching half health, you can keep him from manually returning to his Rune of Travel and give you and your team time to finish him off.
Don't use the Solar Blessing talent when fighting Willo! She can simply place her Dead Zone on top of where your Pyre Strike stops and completely negate the healing.
