Reverse Engineered Ward
You can place this ward from a distance (Less than Farsight Alteration). When placed it goes instantly invisible. Lasts short time (20-30 seconds). Can carry only one. Costs 100-200 gold. Reverse Engineered Ward can disable enemy wards and make them provide enemy team with sight from just a moment before RE Ward was dropped. So for example, you could drop RE Ward at Baron and take it without enemies knowing that someone is even there cause they think they are safe but they only see the fake vision from their wards while your team takes free Baron. This would be perfect weapon for taking early Dragons, Barons and Herald.
