Forgotten Tales

My idea is to start a new fight System. some weapons should hhae special effects for example firebow makes burning damage. Other effects could be posion,freeze,double hit...
The effects should be activated once every minute.theire could be also sell anti Posion etc.in the shops. This effects also should have some npcs

ealemental attaks, elementals défenses, it wasnt suggested alredy? because i love this idea, maybe the title no go on sens i think u mean...
