Doom Elite – Kill Doom Elites with low troop loss with low Virus Resistance
If you have a low virus resistance, given the huge Damage Dealt debuff, a rally against a doom elite will cause a huge loss of troops, regardless of success or defeat.
To avoid that, you can ask help from your allies:
- Create a 1 hero squad, with the hero that has the lowest command attribute (so to bring along less troops)
- Launch rally on doom elite monsters, asking to participate to those that have enough Virus Resistance to be able to kill the zombie
With this approach you defeat the zombie and therefore you earn a lot of mutant crystals 
, with a minimum troop loss.
