Toxic blowpipe

Special attack
The toxic blowpipe has a special attack, Toxic Siphon, which increases damage by 50%, while healing the user by half of the damage dealt (rounded down). This consumes 50% of the player's special attack energy.

Trivia

 * In PvP situations upon release, the toxic blowpipe's attack speed was 8 on rapid, meaning it was able to attack every 1.2 seconds, which made it easy to overpower another opponent in player-versus-player combat. This was fixed in an update the next day so that the blowpipe's speed on rapid would be equal to that of a shortbow only in PvP; player-versus-monster encounters remain unaffected.
 * Prior to an update on 16 November 2017, the blowpipe envenomed NPCs at the same rate as envenoming players at a rate of 1 in 4 (25%) regardless of whether a serpentine helm was worn.
