How does unstoppable/overload work now?

[cerulean goblet]

It says Solar ignitions will stun now but on the same page it says I don't have such anti Champion capabilities equipped even though I have my throwing knives that can ignite and scorch

what gives?

[sacred ridge]

if you cause an ignition is stun the champ

i used warlock fusion nades to stun unstoppable's though its not really a thing i would use outside emergency need since takes both nades

[warped totem]

yeah it just says that but you should be able to stun
