You see a poison dagger (Atk:16 physical +2 earth, Def:8). Classification: 1 Tier: 0. It weighs 8.80 oz.
I've been looking for good training weapon for knight to increase blood hit rate and identified poison dagger as good candidate thanks to it's additional earth damage.
According to tibia fandom: "Since the Winter Update 2007, this dagger causes earth damage, which does 1 damage each turn and lasts approximately 1 turn for every 10 damage done to the creature. The harder the hit, the longer the creature is poisoned. [...]" and tibia-wiki describes it as it deals 1hp/turn earth damage.
I tried it on monsters weak to Earth Damage, like Cyclops and I can not see any additional damage being delt.
I checked Serpent Sword as it has same attribute and it works perfectly fine.
Any ideas?
