Radioisotope Injectors come in many types: 1: Manual. There are 3 tiers of Manual Radioinjectors. These are early game, very cheap to create, but slow and low durability, at only 25, regardless of tier. 2: Piston. These are the most versatile, as there are 20 different variations of them, made using different combinations of rods and isotopes. Each have 300 durability, regardless of tier. 3: High Speed. These are more expensive, but are higher damage and higher durability than piston radioinjectors (dependent on tier). They have high attack speeds (the highest of all radioinjectors) 4: Rodless. These are low attack damage, however high durability radioinjectors meant for dealing a dose of radiation without dealing too much initial injection damage. They have the highest durability. 5: Fission & Fusion. These are extremely expensive, however are the most powerful, dealing 30 initial damage, However capped at 0.5 attack speed, making them the slowest. Fission deals a massive dose, however Fusion has a much higher durability, at the cost of a lower dose.
