They don't?
Well I'll be damned.
And Thresh.
name a mage champ that has basic attacks that do magic damage (besides corki)
So no
Even if mages CHANPIONS don't do Magic damage on basics. I think it would be cool if caster minions did magic damage.
Magic doesn't exist, and it's childish to believe in such a thing
btw I think some minions do deal magic or mixed damage
Downvoted for incorrect use of meme.
STACKS MR AGAINST MALZAHAR VOIDLINGS DO 1.2K DAMAGE
RIOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOT
I like to imagine they're not actually mages, they're actually just children pretending to be wizards and throwing rocks at people shouting ABRA CADABRA.
...and that Im beating them up and taking their lunch money.
they're not mage minions, they're caster minions, and in this case in particular, AD casters!
Rework Banner of Command to only make immune from champion magic damage. Make caster minions do magic damage, and laser turrets also magic damage (adjust numbers as needed for balance). I think it could work, and make Full armor tanks think harder about diving the double nexus turrets.
Wrong meme.
This is bad, and you should feel bad.

Towers shoot bolts of energy. Should at least be magic dmg if not true dmg.
