Archelon init guide

Update due to current gameplay:

As Initiator, you can ss Rock (remove its immunity) by using Smog Ball on Rock when Crack, before Revolving Blast.
You need to MT, so when Cracked, use MT immediately then Smog Ball. Don’t forget to target Rock. Chain 10 helps you rotate skills.

As Initiator, you can also tank with enough stats (9k+ DEF, 800+ Soil DEF), hate and Guard (explorer skill). Make sure you can still MT on time (better let someone else ss).
Use Guard before Charge and Earthquake in Phase1, before the attack after Set in Phase2 (when you see Warning)

Feel free to adjust your deck depending on the need, just make sure it has all needed and is comfortable to do your job.
