Magneto SP3 damage potential

Rajdeep1997

So the magneto buff is out and red magneto can do devastation damage from sp3 in bleed immune metal matchups, but there is no champion out there who can really survive after that damage just like guradian would deal that blast of sp2 after bunch of sp3. i tried in ROL and vision died in first hit, can any one notify us regarding the max damage possible by magneto against a metal bleed immune and a only bleed immune champ...as no one knows till now...

Think I seen a r1 or r2 unduped do 492k with 35 prowess against ROL vision over on reddit.

A r5 will probably do North of a million or 2
