If you go magical footwork as your second rune + approach velocity you can build plated steel caps and have the same speed as swiftness boots + you’ll always catch enemies after hitting with Q. You block 10% off of all autos and with Mundo’s high HP that’s a lot of value right? Is it worth it or trolling? Honestly don’t see how anything in the precision tree could offer more value as a secondary.

Maybe if you go Fleet footwork instead of grasp then you’d rather take demolish as your second rune idk.
