Now i've tried to clear ebf on normal solo on every hero type. I've done this with the dd by changing its itembuild from only damage items to just heart, cuirass, vladmir, sange and yasha, and desolator. Tank heroes hasn't changed at all, i just bought heart,cuirass, and vladmir(upgrade to blood gem) as well, and buy blademail and bloodstone / sange and yasha when it's needed. But how can i solo win on casters like qop, cm and so on? Earlier i just bought base octarine, veil, kaya and sange and then the yellow heart at first cause bloodstone didn't give as much spell lifesteal as needed, bosses were strong, and my characters had enough magic damage and mana for early waves just to fight normally till buying normal magic damage items, but now it doesn't matter what items i buy, i don't have enough mana to fight bosses. I spend all the mana to just take half of hp (talking about the roshan, leshrac beating for 5 minutes minimum and golem, cause i haven't passed through the golem on queen of pain specifically).
Can you share what itembuild can be universal for casters to win ebf solo?
