 Using 'block' with the right level (high, middle, low) will give you a great chance to block the next hit. If so, you won't loose HP, and you'll take the advantage for the next round.. Be careful though, if for instance you block high and your opponent attacks you low or middle, you'll have 100% chance of taking the hit (Except if the strike fails). Blocking chance depend on your stance.
 
 There's a chance for fighters to fall down. In this case, hits will be much less powerful, and your opponent will do huge damage. If both fighters are on the ground, then one of them will be above the other. (The second fighter to fall will be above. Then, the one with the advantage will be above.) You'll have to use the '**!action standup**' command in order to .. stand up :)
