A negative item

I don't know if this is a good idea, but what about adding an item in Dota that gives negative effects? This item would deal a bit of damage each turn or poison the carrier, and the only way to get rid of it would be to pass it on via basic attack. You cannot sell or drop these items. Also if the carrier dies, the item is destroyed and the kill is credited to the previous owner. All negative items are unique and do not stack with other negative items. Negative items are out of stock the first 4 minutes of the game.

Possible item

Blood-Sucking Orb
Costs: 600 gold (requires Secret Shop)
Passive: Each second this item deals 10 pure damage, but breaks after a minute (dealing a total of 600 damage in total), but can be spread via basic attack (30% if melee, 20% range). This item also cuts any regeneration in half (Does not stack with multiple Spike Balls)

Toxicity Orb
Cost: 300 gold (Secret Shop)
Passive: Poisons the target (dealing 5% of the total health but will not go under 10% of full health) Also slows the target movement speed by 8%

Blindness Orb
Cost: 250 gold (Secret Shop)
Passive: Cuts enemy targets vision by 25%. IF the target has a vision increasing ability or item, it's vision is cut by 50%. Does not stack.

Beacon Orb
Cost: 450 gold (Secret Shop)
Passive: Gives true sight to the holder of this item (to the enemy team).

Spirit-Crusher Orb
cost: 550 gold (secret shop)
Passive: Doubles the waiting time of all abilities, while increasing the mana use by 50%.

I don't think it's a good idea for the general gameplay of Dota: 1000-2000 is a lot early on, and it would give a huge advantage to mobile Heroes (who can pass it in a second) and nerfing - though indirectly - slow supports and carries without escape/initiation mechanisms. Plus I don't like the fact it gets destroyed after its carrier dies, because you might end up spending 2000 gold for killing a support that just gets it and sits back until he dies. It's not an overall bad idea, I just think it doesn't fit well in a game like Dota.

ok, i will change it up a bit

This spike ball could be bought with starting gold and used to one hit some characters. - .-

Make it that it's out of stock the first 3-5 minutes! :D And make them all unqiue negative items! :D or else people will spam buy spike ball and venom balls for easy kills!
