Make a beginning item that would temporary let champions use all three abilities
Its purpose is for use before minions spawn. It could work right when you get it or it could have an active. Right when the second wave spawns it can turn off and not be used again. It would be good for nothing. I would say make it free of gold so summoners can still buy their lane items or make it cost 50 gold so summoners can not buy a starting potion. I find it annoying when their is a jg team fight before minions spawn and I only have one ability to fight with. Some how summoners should have two of their abilities silenced if they attack a jg camp for a short duration about 5 seconds so they can't use the abilities on jg camps just champions. I guess if the jgler is alone and ready to take first camp and is out numbered. this jgler would be forced to retreat or ping for the team. At this point the jgler may not have the item nor anyone else on the team. It makes some decision making. If the jgler is starting top and doesn't take the item, then perhaps the top laner would. Then this would take communication before the team leaves the store.
