Buy RS3 Abyssal armour spikes
Abyssal armour spikes are a consumable item in RuneScape 3. They are made by upgrading armour spikes with abyssal flesh. Carry them in your backpack or ammo slot while wearing melee gear. They will then deal damage to any enemy that attacks you from an adjacent tile or with a melee attack.
These spikes also apply the Abyssal Parasite bleed effect, the same effect found on the abyssal scourge. Each damaging hit from the spikes adds one parasite stack to the target. Each stack deals 18.74 to 31.24 bleed damage, up to 50 stacks. The bleed hits every 1.8 seconds for 9 seconds in total. New stacks refresh the timer. Missed or blocked hits do not add stacks.
If a target dies with the effect active, the bleed spreads to enemies in a 5x5 area around it with half the stacks. This spread does not work in PvP. Unlike other bleeds, many players can attack the same target without resetting the damage. The spikes also keep the normal effect of standard armour spikes.
Making them takes level 90 Smithing, which can be boosted. Combining 10 abyssal flesh with 100 armour spikes gives 100 abyssal armour spikes.
