Damage elixir bug

[Cinco]

i used x5 dmg buff and died to 4 or less zombies in an instant in old quarter campaign lol

The damage elixir does nothing for your defense - it adds damage. Also you need to keep in mind that your blood powers your abilities so if you are spamming them you will be more likely to die (as your blood has run out).

Don't let the zombies hit you so often. You may also want to consider whether or not to use a defensive elixir (something that gives you armor, for instance) to withstand beatings from the zombies.
