Elysis is a top-down action-RPG which aims to provide a gratifying sense of combat and exploration. To achieve this, the addon system was conceived as a way to allow players to modify their weapons to be able to fight a wide variety of enemies. These addons will give weapons special properties and will be scattered throughout the world waiting to be found.
The combination in the pic: Boomerang + Bomb + Remote Detonator + RedVulsin.
With this you can carry bombs with your boomerang towards the enemy and then detonate it on them while leaving some fire around which burns anything that survives the blast.
