Potion of antidote is useless, its ment to counter the posion potion but it takes so long to drink and I have never seen anyone use it ever. Making it splash would give it use and a good counter to posion potions as they are stupidly OP when paird with flame totems in a group fight!
Change antidote to splash not drink, dosent matter if your potion effects only yourself, teamates or enimies aswell,
