Abyssal vine whip

The abyssal vine whip is an abyssal whip with a whip vine attached to it. It requires 85 Attack and 80 Slayer to wield.

The vine itself can be traded, but the abyssal vine whip is not tradeable. You can attach the vine to dyed whips too. The vine may be removed from the whip at any time using the "split" option.

The vine whip has slightly improved stats compared to the regular abyssal whip - it has an additional +4 Slash Attack Bonus and +2 Strength Bonus. It also has a chance to inflict poison starting at 48 damage. Furthermore, it has a more damaging special attack (see below).

Special Attack
The abyssal vine whip has a special attack, Vine Call. The attack summons a vine that strikes the target 10 times (after the initial hit, which functions the same as the rest of the vine hits - so 11 hits total) with 125% of the user's accuracy and 20% of their strength. This strength can be increased by wielding another weapon after using the special attack due to an unintended glitch. With the use of a recover special potion or a ring of vigour the special attack can be used two times in a row, however only one vine can be summoned at a time so if the vine from the first special attack is still going the second special attack will cause the first one to disapear. The attacks will only hit as long as the target is in range and can hit up to three targets in a Multi-way combat zone. Additionally, Vine Call may poison the opponent starting at 48 damage. The special attack uses 60% of the special attack bar.

Trivia

 * It currently has the highest attack level requirement among non-Dungeoneering weapons, just beating chaotic weaponry at 80, as well as the highest slayer level requirement among non-Dungeoneering weapons.
 * The special attack's damage is boosted by the effect of the ferocious ring while in Kuradal's dungeon.
 * There is currently a glitch with wearing a ring of vigour and performing the special attack of the Abyssal vine whip. Rather than reducing the cost of the special attack to 54% (a 10% reduction), the special attack cost is only reduced to 56%; fortunately it is still possible to do back to back special attacks even without the proper reduction.
 * There currently is a glitch with the special attack in PvP. If you have a familiar and are in multi combat PvP and use the special attack, it will cause damage to your own familiar causing you to become skulled. This has yet to be fixed.
 * "Vine Call" can negate a strykewyrm's special attack if timed correctly. Whether or not this is a glitch is unknown.
 * The special attack takes on the abilities/stats of the weapon wielded while the special attack is in effect. This includes special effects, such as the barrows set effects. Therefore it may be wise to switch to a weapon with a very high strengh bonus, such as the chaotic maul. If the vine whip special attack is used and then veracs armour is equipped, then the limits on the special attack damage seem to be removed. This also enables the special attack to damage enemies such as the Jade vine in Ardougne. These effects are confirmed to be a glitch.
