Exana pox is not working

Simple as that, words come out as normal text.
-doesnt waste mana
-doesnt heal poison
-makes you mute over time (xD)

Hehe idk why but its not a spell here, not all tibia's normal spells are used here.

So its just not part of the game? neither is Light (many people just use ambient light tho...) but anyways, i dont even recall being able to buy antidote potions/runes @NPC, and i know it may sound ridiculous at first (with monsters like poison spiders that poison for mere 2hp/turn) but what on the long run? GS, Wyverns and other creatures can make a good deal of damage out of poison
