Buy RS3 Primal armour spikes
Primal armour spikes are a consumable item in RuneScape 3. They deal damage to enemies that attack you from adjacent tiles or with melee attacks. You can carry them in your backpack or equip them in the ammo slot. Either way, the effect works the same.
To trigger the spikes, you must use only melee weapons and wear melee torso and leg armour. One spike is used each time the effect goes off. Each hit deals typeless damage equal to 1.25 times your current Smithing level, including boosts. A shield doubles the damage, and a defender adds 50 percent. The spikes also have a 10 percent chance to deal 11 times the normal damage. On average, they hit 2.5 times harder than regular armour spikes.
These spikes can be added to a Nodon spike harness. They can also be combined with abyssal flesh to make primal abyssal armour spikes, which add a melee bleed effect. If a monster dies from spike damage alone, you get credit for the kill and the experience that comes with it.
Primal armour spikes are a strong pick for melee training and AFK combat, since they punish every enemy that hits you.
