"Looks like we have an escapee, gentlemen. Subject 32765 escaped the facility in 713.1 seconds. Be warned she has the trophy and is on the move. I'll go start the car, you grab the guns. The trophy will be ours again."
Not much history here. Achilles was invincible except for his heel, which no one struck in this game. He was invincible because his mother dipped him in the River Styx, but she held onto his heels, so they didn't get dipped. And he was a Greek, not a Trojan.
1)Pick Virus. 2)Start in Canada, New Zealand, Cuba, Greenland, or Madagascar. If you do not get there restart. 3)Sell starting symptoms, if any, and buy sneezing (unless it is what you started with, just keep it). 4)Buy 1-1-1-0 resistances but no transmissions (they trigger closures). 5) Once three countries are infected, sell sneezing to get rid of visibility. 6)Wait until all countries are infected. If Madagascar closes its shipyards or is not infected in 30 days, restart. 7)Buy all four drug resistances, sneezing, coughing, and vomiting. 8)After a few days, unlock tiers 2-3, keeping whatever symptoms it gives you. 9)Buy fever, fatigue, diarrhea, pulmonary edema, and hypersensitivity. 10): Wait until everyone dies.

Spells: (also level 5) : Meteor Strike, Comet Shoot, Rain of Arrows, Pheonix, Lightning Bolt, healing potion. Use Grullborg Grimtooth level 30 to be able to equip all of them.
