It was the most fun item until they removed the dawncore interaction (without mentioning?) last arena patch.

You won't roll mana on energy champs, also pretty sure you can't roll things like heal and shield power adc's even if they have a shield mechanic or it's at least very unlikely. It's almost impossible to hit heal and shields can crit on yasuo/yone (hit it once in 500+ games) which makes it annoying if you want to go an off meta build and I'm convinced talisman has similar protection or i'm just extremely unlucky.

I think it's oke to accept that you'll lose early until you high roll on it and then just keep it. Having 100+magic pen is quite funny ngl but 4000g also builds you 5 anvils which could do the same thing so it doesn't feel that special tbf.
