Weaponry
A huge variety of different weapon types and individual weapons may be used in Avaria. Each particular weapon comes with its own style, drawbacks, abilities, and general intricacies. A heavier weapon will generally be slower to swing. A lighter weapon will be quicker and allow you to riposte, but perhaps fail to deal the intensive damage that, say, a two-handed battleaxe might regularly be capable of inflicting.
You can STUDY all weapons that you're holding in order to get a fairly good understanding of their physical traits, but you will need to learn how to use a weapon -- in other words, to invest points in its related skill -- to truly comprehend its abilities. As you learn and improve your skill with a weapon, you will gradually gain abilities that unlock moves you can use in combat. Some moves will be passive, others will be wind-up moves in order to prepare for other moves, and still others will be very powerful combat-finishers.
