Talon's Q Interaction with deathfire keystone, and corrupting potion.
Talon's Q Bleed is a spell and it does damage so there isn't any reason that iit shouldn't apply these effects.
But it currently does not apply these effects, and it needs to be fixed. To counteract any 'that would be really strong!'
Not really, thunderlord's is still very advantageous for him because of the instant damage, and Brand's passive also applies it. On every spell. And lasts 4 seconds. And applies liandrys AND rylai's.
