I use a Rogue's Ring when farming so I can get Steal +3 with its latent effect, which requires 75% or lower Hit Points and fewer than 100 Tactical Points. But if I run past a pixie with 75% or less HP, I get a free cure, even when I have /blockaid on! While I know the pixie means well, it does ruin my day.

My suggestion is to have /blockaid apply to pixies as well as other players. Otherwise I'll have to run around with a big supply of venom potions to keep myself injured.
