i used to poison my arrows frequently, despite the fact that poison damage does not work.

it now appears i can not poison any kind of arrow, and this is making me sad.

daggers, spears, and projectiles may be poisoned.

Thanks for reporting this, going to inform the developers of this.

Times change - so do people and missiles also,
society noticed that its not worth to be toxic and arrows took example, gud arrows.
