Throwing the leviathan axe will not inflict permafrost onto entities

Throw the leviathan axe at any mob

Axe throw should permafrost mobs hit

Yo just on a side note I found the coolest easter egg when using both Mjolnir and Leviathan axe and I'm telling you that was the coolest thing ever lmao :D

Glad you liked it, is the issue a consistent thing or just at some random times? Since it all works fine on my end.

It is consistent, and by permafrost I mean the effect, not the cool explosion thing it does when it hits an entity

Update: It works when you recall it, but not when you throw it initially.

Do you see particles on the mob when you hit it? Not the explosion ones, but rather snow particles or potion effect ones?

I do not, and when tested with other players it does show potion particles or effect them with the effect, it only deals the damage from the initially throw hit

Nevermind, I found an inconsistency in the code where the explosion is supposed to give the effect, but sometimes it overlooks the entity hit. Has been fixed.
