Some keep fighting, even though they are burning alive!
Greek Fire is all about dealing great damage without killing the enemies outright. Since the damage is dealt over 3 turns, the affected units will, most of the time, keep fighting over a few turns, although they are being consumed by fire.
This projectile will spell a slow, certain doom for your enemies. If your goal is to put an end to a charge-threatening cavalry, a conventional shot would be more appropriate than this one. On the other hand, if you wish to kill slow-advancing and dangerous enemies, this shot is your best option.
Upgrade: Burns for one extra turn, which means a Fire damage of 120 over 4 turns for a Direct Hit and of 60 for a Partial Hit.
