Ideas: (I don't know if there has been any of this before)
Arrow Rain/Shower (Active - Instant)
- fires an arrow to the sky and rain of arrows will fall down from the sky, the hero cannot be damaged. (200 AoE Range)
Travel (Auto-Cast)
- if activated the hero will teleport towards the desired location (right click) instead of walking, but there is a maximum distance for example; the user right clicked a location which is so far, the hero will only teleport what is the maximum distance range and each time the Hero teleport, ___ mana will be drain
