The Elemental Amulet imbues a hero's weapon (both in melee and ranged) with a certain element. Enchanted weapons deal extra damage, and can be very effective against enemies whom are weak against that particular element. Elements include: Acid, Fire, Light (holy), and Lightning. Elemental Amulets can be used in conjunction with other weapon-based items, such as Rapid Fire and Multi-Way Shot.
The Elemental Amulets are shot-based.
The Elemental Amulets are timer-based.
