Counter
You have a chance to counter an enemy's attack with one of your own. At creation, you must choose whether you want to counter attacks made with weapons or special attacks. Weapon attacks include all attacks made with weapons, including unarmed attacks, Weapon Techs, and weapon-related Command Skills such as Jump or Deathblow. Special attacks include various other Command Skills and Techs, such as Slots, Stat Breaks, and Magic Attack Techs. Special attacks may also include other forms of attack as the master sees fit - for example, a rod that fires bolts of energy may be considered a special attack, rather than a weapon attack. You must also choose one of the following methods to counter with:
Normal attack (30% chance): You make a normal attack roll, dealing damage as normal if you hit.
Command Skill (30% chance): Choose ANY Command Skill. It may be the Command Skill your character normally knows, or it may be a completely different one; the only restriction is that Chakra and Health are not allowed as Counter Skills. When the counter is activated, the Command Skill takes effect as it normally would.
Tech (20% chance): You counter with a Tech, paying the MP cost as normal. You must either choose a specific Tech that you always counter with, or you may counter with any Tech you choose - this decision is up to the Master.
Mirror Tech (20% chance): The attack you counter with is exactly the same as the one used by the attacker, but uses your Strength or Magic to determine its effects. You must pay any MP cost associated with the power. At the Master's option, a Mirror Tech may carry a different elemental affinity than the original attack, or it may automatically be of the opposing element. Mirror Techs cannot counter normal attacks.
Using a Counter skill requires no expenditure of Speed Points. You do not have to counterattack if you do not wish to do so. Note that counterattacks cannot be countered in return.
Ok, so… Why is it that using a Tech as a counter has a worse chance than using a Command Skill? I mean, considering you can counter with ANY Command Skill, not just the one you actually have, there's no reason to choose the Tech Counter when you can take the Command Counter and choose to counter with X-Magic. Not only will you be able to deal more damage, the chances of triggering the counter are better.
