The key items (if possible non-premium) needed to complete today’s raid without receiving any damage.
Today for tier 4 you need 2-3 of the following items (special note: no premium items needed at all today!):
1.) Absolutely needed for the minion mechs and the boss:
Drop the bomb in the first round to shutdown the minion mechs and the boss all starting in range 3 for the rest of the battle.
2.) Alternatively needed for the 1st tank starting at distance 7:
- Savagery + arena bonus on heat damage -> overheat the tank only allowing it to come 3 spaces closer in the first round and then be destroyed by your 2nd turn.
- Hysteria -> drain the tank even without arena bonus only allowing it to come 6 spaces closer to be annihilated by you in your 2nd turn
- Reckless Beam + arena bonus on physical damage (max damage 283 * 1.2 = 339.6 = 340 > 326 HP + 3 PhysRes) -> can one-shot the tank with luck (reloading often enough) with the first move
3.) Alternatively needed for the 2nd tank with starting distance 5:
- Reckless Beam -> same situation as above
- Night Eagle (max damage without bonus already 336) -> can one-shot the tank
- Grim Cobra with enough arena bonus on Electrical damage (290 * 1.2 = 348 max damage > 326 HP + 2 ElRes) -> can one-shot the tank
- Supreme Cannon with some arena bonus on Explosive Damage (315 + up to 20% = 378 > 326 HP + 2 ExRes) -> can one-shot the tank
- Desolation with some arena bonus on Explosive Damage (310 + up to 20% = 372 > 326 HP + 2 ExRes) -> can one-shot the tank
So put on enough heat modules for heat bomb and then flatten the raid troops without taking any damage - all without a single premium item today.
