Heavens halberd. Stronger than ever now. I have played couple of games now as a support main, one vs ursa who refused to buy bkb so I bought halberd (along with euls ofc), and another game, TA refusing to buy bkb, I bought halberd and she was so clueless.
Its even buffed in latest patch so its kinda OP vs non bkb buying adamant cores.
