I have a idea of a weapon that uses 10%-15% of your health, and gives a stronger damage to the enemy. No energy, no heat needed

Sacrificeful weapons are weapons that uses a portion of your health. These weapons are good for Final attacks, or use it many times for your own will. The weapon will be disabled if your health is under 10%.

Weapons:
Kamikaze Discharger - Lvl 5 - Dmg: 28 - 39 - Range: 3 - Knockback: 1 - Needs: -10% Health per use - Price: 3,000
Kamikaze Discharger II- Lvl 12 - Dmg: 45 - 55 - Range: 3 - Knockback: 1 - Needs: -10% health per use - Price: 9,000
Kamikaze Discharger III- Lvl 25 - Dmg: 62 - 78 - Range: 3 - Knockback: 1 - Needs: -10% health per use - Price: 15,000

Also a weapon I suggested that uses ALL of your energy, but uses the mininum damage if under 50% energy, 81 - 109 if over 50% and 110 if Full energy (100%)
Final blow - Lvl 40 - Dmg: 80 - 110 - Range: 3 - Knockback: 1 - Needs: All of your remaining energy - Price: 24,000

Leave a comment. If some of my suggested weapons are overpowered, or something that doesn't fit it, feel free to ballance or change the stuff on it. Thanks!
