3. An item, made from wire, bones and some metals, that when is thrown, and upon hitting ground, summons a frienly robot-skeleton that attacks your enemies whit a shortsword and has limited lifespawn, meaning it dies after about 1 minute. It would be in the same team as you are, and lifespawn would be shown below hotbar, nexs to buffs, or below them. Limited amount of them used by one person.
4. Goblin/gremlin granade/mine. A granade/mine that suicide-attack enemies near it. Either trown or plased, explodes like a granade. I personally think gremlin granade sounds cool. Might be able to fly, but then it would be named fairy bomb.
