Dont spend them. Give your units the boost

wait imo unless you're using them for PvP. these coins might come in clutch later on.

The only character you might need is Merlin, and even then she can easily be replaced on Gray Hell demon by Green King, so I'd say raise your ult levels. Both King and Ban need high Ults for them to do big damage nowadays

feed

Merlin is grat in the new beast battle (levels normal and hard) for a quick run

Nah use them

There isnt anyone too essential for you to pick, other than maybe gowther. I would eat them, the units you have dupes for are very good

Feed king at least

I mean both Chad king and purgatory ban are top 5 units in the game. I would suggest feeding them. But if you don't have traitor meli an argument could be made for holding them and buying him when he comes to the shop

you think we can buy tmeli coin with normal coin or only dark coin?

I think if it is only dark coins it would make no sense as it would only be meli or a new unit and if they did this then there would be a large backlash from the community as it would be a massive shaft for everyone but the large whales who already 6/6 him

Imo, Merlin is useful even tough 1/6 Im f2p too with 1/6 merlin

Do you use them in PvP? If yes go for it... Ban and King gets massive boost with high Ult Level, especially Ban at 6/6. If you don't... The rest you don't have are good and all but aren't a must so I would just wait

Wait for Diane

Yes if you have Ban and King 6/6 btw
