Ah Relics. Everyone's favorite corner of Mcoc. So I have most of my 6* relics at Rank 2. With how expensive/rare materials are to take to rank 3, I haven't done any yet. But I do have a 'free' r2-r3 gem, and I'm interested in starting to buy more of the materials to upgrade, IF they seem to have a major benefit.
But that's the thing, I just don't know how beneficial they are from r2 to r3 and which ones benefit more or which ones are pretty inconsequential/useless.
For example, I have a duped Venom relic on my Venom. I feel like he would be a good recipient of a rank up. But so would my duped Iron Fist on America Chavez. Hulkbuster (unduped) for Guardian, Hulk, and Thor also seem like good relics to upgrade.
Can anyone who has much more experience or a better handle on relics share some insight as to how much of a difference the rank ups make? Thanks
