If the combo has a *, it is combat tested, if it isn't, try it out against AI, then human players,don't use immediately.. If >, I made this myself
Feel free to add your own (Should we have a dedicated wiki page for all strategies?)
These are the combos,
Hermit+Venom+Recluse. Assault line*
Used against slashers, or attacking enemy bases, Venom stuns, Hermit shields, Recluse destroys, very hardy to kill as it has lots of HP, can stun, and if needed, provide cover fire
Redback+Venom+Recluse+Weaver. Bow&Halberd.*,>
Redback is used as it does lots of damage, kills enemy units, Venom keeps them still and stunned, keeps enemy from firing, and makes easier for Recluse to deal massive damage. Weaver heals and salvages.
Flea+Venom.
Made by @snugglebass, Venom stuns, Flea, with it's amazing DPS:Metal, kills as it attacks in groups. Useless vs Riots. Not tested.
Crabe+Redback,>
Riot/Skirm+Riot. Not tested due to hard to single. Redback does killing, Crabe does everything ranged.
Hermit*
Spam Hermits. Been tested a lot.
Any more?
