1. Removing mana cost of searing arrows, frost arrows and poison attack(viper) since this skills are never picked in my experience, but keep them as orb effects.
2. Increase or remove the target limit for searing chains.
3. Mana void cooldown reduction to 30 or 40 seconds.
A very minor buff to a very situational and unpicked skill.
4. Land mines should require at least 3 seconds after cast to activate (to nerf face planting a bomb since it is very easy to deal 600 dmg with positioning skills or a stun).
5. Vendetta cooldown reduction to 30 or 40 seconds.
6. Double edge damages the caster by half of its damage.
7. Rot self damage reduced to 75%.
