attack and defense basics

[Zechnophobe]

Crits cause you to deal 150% of MAXIMUM damage which is very important to know. This means that units with large damage ranges will crit for more than ones with smaller ones.

For example, an ice spiders deals 5 to 5 damage, and crits for 7.5. It's got an average of 5 damage before firing, and 7.5 on crits

A unit that deals 4-6 damage crits for 9 (150% of 6). It has the same average damage as the ice spider, but deals 33% more on a crit!

Also you should realize that the bonus to damage is based on the difference in attack and defense, not the absolute value. This means that decreasing a Black Dragons defense by half (35) is much MUCH more effective than decreasing a dragonfly's defense by half (2). This is why a max strength helplessness can be so incredibly effective against high defense targets.
