Season 3 is starting with a bang! Mithril is scarce and virus resistance is low, but fear not! 

Follow these tips to rise quickly:

Generic suggestions: 

• Let's use War Fever to increase power by 1% with each attack (not possible at the very beginning with all those shields!)

• Brothers and Sisters, remember that when we rally, the leader's virus resistance protects the whole squad! Use this to conquer those Digging Strongholds and reap the Mithril rewards!

• If your virus resistance is low, don't despair! Ask your brothers and sisters with higher resistance to join your rally against those Doom Elites. You start the rally with a single hero squad, and your allies with high virus resistance join in to crush the Doom Elite and claim those sweet first kill rewards!

• Prioritize acquiring Scarlett and Universal Epic shards from stores as soon as they become available. These shards are crucial for upgrading during UR events.  

• At Season Start we'll have two tickets to swap EXP and stars between two UR heroes. This means we can make two exchanges, so start thinking about which ones you want to do. For example, I will definitely replace Stetman with Marsenne or Violet. A good strategy would also be to transform Scarlet into a UR in season 3 (second week) and then exchange her with some other REAL UR hero that we still have at a low level. 

Precious Resources:

1. Mithril and Sacred Water:

   • Protector's Field: Take it to level 10 and STOP! From level 11 it requires Mithril and Sacred Water, which we need for other seasonal buildings. Level 10 already gives us all the Desert Protectors' features.

   • Recruitment Ticket: Conserve your hero return tickets during Seasons 1 and 2. Use them at the beginning of Season 3, where even a small amount of mithril or sacred water can make a significant difference. 

   • Radar: Let's start Season 3 with stacked Radar missions to get a Desert Ruin mission (gives us Mithril).

   • Doom Walker: Don't attack it after the reset on the day your server receives Season 3. Wait for Season 3 to start and then kill the highest level you can to get a lot of Mithril as first blood. Do this every day, level 190 gives 207k Mithril as first blood, no need to kill higher levels as they don't give more Mithril than 190. 

   • Zombies: Let's attack small zombies up to level 3 right away, they don't require curse resistance and give us first kill rewards. Remember that small zombies have a type (tank/missile/aircraft) and so damage debuffs apply.

   • Blessing Fountains: Let's upgrade them all only to level 15 until we've unlocked them all (4 + 1 additional with the weekly pass), then take them all to 16, then all to 17, etc. Every time we reach level 15 of a Blessing Fountain, the next one is unlocked.

   • Digging Strongholds: Let's capture them ASAP, they provide hourly Mithril to all alliance members. Remember to always collect the Mithril, to do so go to Alliance button -> Alliance Cities -> Digging Strongholds tab and click on Claim all hourly.

   • Sandworm: When we kill it, it drops reward chests containing Sandworm Scales. Let's collect them and go to the Desert Bazaar to buy Mithril and Sacred Water.

   • Professional Skill "Trap Landmine": Allows us to catch sandworms. Let's go on the map and watch it at different zoom levels, at some point we'll see sandworms moving, let's track one and the moment it changes direction intercept it a few tiles ahead with the trap landmine. The trap must be placed in its path and not right on it to work.

Extra Mithril and Sacred Water:

• After each level up of the Curse Research Lab, let's check for rewards in Season 3-> Season 3 main banner-> Goals-> Individual (often it doesn't show the red dot notification).

• Once we've captured a Digging Stronghold: Alliance button -> Alliance Cities -> Digging Strongholds tab.

• Once our Alliance Center has reached level 5: Alliance button -> Alliance Center -> Mithril Plant, let's collect the Mithril.

Purchases:

• Let's buy the season battle pass and weekly pass right away if we want.

• Let's buy the Mithril packs, they're available only the first week and even if it says availability is 1, we can actually buy multiple packs, but each pack progressively doubles in cost and Mithril amount (~ 5/10/20/50 $).

• If possible, let's acquire the "Eternal Pyramid" decoration as it gives a boost as described in Season 3 -> Season 3 Banner -> Desert Blessing.
