For anyone else who needs to change the testnet it's relatively straightforward by

• Updating the 2_mycontact_migration file
• Add the HDWalletProvider to the truffle-config

Kovan testnet does not appear to be supported by opensea for the NFT display
Ropsten testnet does not appear to be supported by chainlink for the random number generation

Do you have any testnet rinkeby in your wallet? It looks like you're getting gas errors.

from dungeons-and-dragons-nft.

Yes I am having gas errors. I tried obtaining test ether

I am using a new wallet, and I am new to this space

from dungeons-and-dragons-nft.

Is there a better way to obtain testnet rinkeby in my wallet ?

from dungeons-and-dragons-nft.

It takes a really long time actually to obtain test ether tokens in rinkeby faucet. Can I try doing this with Ropsten or Kovan test network?

from dungeons-and-dragons-nft.

You should be able to get testnet ETH quickly. Kovan might be faster.

Maybe this video would help? I would recommend kovan or rinkeby over ropsten though.
