Dota 2/Kaldr the Ancient Apparition

Ancient Apparition is a ranged intelligence hero that is usually played as a support. He has a good slow with his Ice Vortex, while he can force enemy's to behave differently with his Cold Feet. He can buff up his allies with Chilling Touch. With his Ice Blast, he can assist a teamfight from anywhere on the map, frostbiting enemies until they shatter.

Cold Feet
Cold Feet places a debuff on the targeted enemy unit, which does damage over time. The debuff will be dispelled by moving a certain distance from the initial cast spot, but if the target doesn't move away after 4 seconds they will be stunned. While any decent enemy will try to get out of the debuff range before they get stunned, you can force them to move away from their current spot, which can be useful for harassment or to scare off powerful threats during teamfights. If they don't move away, you will likely get a kill if you have teammates with you.

Ice Vortex
Ice Vortex chills the targeted area for 12 seconds. Enemies entering the vortexed area will be slowed as well as have their magic resistance reduced. Since the cooldown is only 6 seconds while its duration is 12, you can always have 2 vortexed areas at the same time. It synergises really well with Cold Feet, since it slows enemies down, preventing them from dispeling the debuff.

Chilling Touch
Chilling Touch buffs any allied heroes in the targeted area with bonus magic damage for a certain amount of physical attacks. However, their attack speed will also be slowed by 15%. It is useful for buffing up your lane partner when laning, letting them last-hit easier. Unfortunately, you usually won't be using it after the early game, as the attack slow is too much to make the bonus magic damage worthwhile.
 * Ability: Target Point
 * Damage Type: Magical
 * Radius: 625
 * Max Attacks: 2 / 3 / 4 / 5
 * Damage: 50 / 60 / 70 / 80

 * Cooldown: 50 / 46 / 42 / 38

Ice Blast
Ice Blast is a unique ultimate. First off, it has global range, meaning that with good prediction you can hit enemies anywhere on the map. Activating the spell will launch an initial tracer shot in the direction of the targeted area. Once the tracer reaches the intended location, using Ice Blast Release will release the second, main projectile. The tracer will show how big the radius of the second blast will be, the further it has travelled, the bigger the blast. Once the second shot hits an enemy they will take damage. Any enemy in the second shot's path and caught in the path will also be frostbitten, making them take damage over time and instantly killing them once their health drops below a certain amount. A very potent but hard to use ultimate. You can launch an Ice Blast from the opposite side of the map to aid in teamfights, an make it much easier to kill the enemy team.
