This section will explain about the differences between the multitude of weapons found throughout the game.
Weapons come in multiple varieties and we will attempt to talk about weapon specials, weapons with guaranteed specials(such as bows), and weapons with built in skills.
Standard weapons are weapons that have a chance to cause a special attack to occur whenever attacking normally or with weapon based armor skills.
Common chances for specials on weapons are 20%, 12%, 10%, and even 5%. Typically these weapons are referred to as 20 proc, 10 proc etc.
Standard weapons receive no special treatment as they are considered the baseline on how to treat the other weapon categories.
0 proc weapons trade their ability to cause weapon specials for a simple damage multiplier. They are considered some of the best weapons offensively for a few very strong reasons.
100 proc weapons are weapons with guaranteed specials. These weapons are typically bows or wands.
100 proc weapons can also sometimes come with a % chance for a "true special". This treats them more or less like standard weapons and overwrites their standard attack for that turn.
Some weapons have the ability to be clicked and attack with a special skill of their own. The damage boost that this provides and the cost occurred depend on the weapon itself.
Weapon skills have recently begun being used in tandem with subrace level 10 transformations or the new Blazing Bloodzerker armor due to how their boosts to weapons allow them to boost these weapon-held skills.
Mechanically weapon skills are treated like 100 proc special attacks where the player uses sp to pay for better damage and sometimes for a status effect as well.
