I am a level 31 myth wizard who is currently in the cave of solitude. So far, I have been struggling a bit throughout this world because there is a lot of myth minions and they like to shield with their storm shields before I get the chance to use my convert spell. Also, any advice on deck setup and gear? So far, I have been using this following:
-prince's peridot deck -helmet of zeus' will -zeus' armor of supremacy -boots of zeus' lore -sky iron hasta -corsair's dirk -spike's amulet of smiting -band of history
Your pet is also an intricate part of your gear makeup too as it affects your stats. I suggest beginning the process of getting a solid myth pet by visiting the hatchmaking kiosk inside the Pet Pavilion.
What I do recommend though is tweaking your deck a little and visiting the bazaar.
Also, if you haven't already, train the spell feint (death; level 26).
At the bazaar, buy the following treasures:
Mass Myth Prisms Myth Prisms Strongs/Giants/Monstrous Mythblades Feints Pierces
Now, on to the strategy.
Here, it is key you have a small deck just for these mob battles. In your side deck, toss a few of the mass myth prisms inside (if more than one enemy is myth), otherwise, have your enchants, a blade or so and a feint stocked inside the side deck.
In your main deck, have a few hummongofrogs, Mythblades, a spiritual blade or two, a troll and a cyclops card. That's it. (Have feint for boss battles)
The key here is to discard (when facing multiple myth mobs) and to draw and use your prism right away. If they shield, don't worry about it.
Blade up, enchant your hummongofrog and attack. The mob with the shield will of course survive, here, you can toss a feint around it and attack with an enchanted cyclops.
Don't be too concerned about their resists at this point. It's only about 30% or so, you can still damage them with the right enchants and a feint.
Myth bosses are different and require the convert to be placed on them immediately. You can also pack a pierce or so in your side deck to break any shields they might have (you're myth!, that's what you do).
