Ok... I got my 10x heroic summon from that recent dwarf event but I don't know when to use it... I'm level 53 and at the moment my team is fairly good, good runes, and good heroes! Icepick, Lord Zomm, Lily Blossom and Koros is my current team. Is there any heroes that are particularly good and I should wait for and would help me in PvP? Thanks for your time.
