Is it okay to have an ability that causes someone to jump 12-20 meters backwards in the air?

In my opinion, no. That is not okay. If you jump 12-20 meters backwards, which is respectively 36 feet to 60 feet, you are going to have broken bones and your character will take fall damage, so I would like your (Ike) input on that.[/quote]

While the question wasn't posed for Yuuji, Y-Yuuji believes that if it's an ability it should be fine. The ability to sustain the damage caused by a 36-60 feet jump should be included in the ability, otherwise it wouldn't be an ability. Whether the ability is a passive or not, the player has to describe in someway, in character, that makes it clear to the readers that the ability was used. Think of it as ability armor. 

Uuu...

Y-Yuuji isn't the best at describing things without examples so...here's an example. The ability being used in the example is a standard fantasy «Shield Charge».

«Shield Charge»
The Knight brings the shield to his shoulder and rushes valiantly forward for several meters. Stuns the target(s) upon impact for several seconds. Damage received while «Shield Charge» is active is reduced by 70%.

Leroy cursed under his breath as the silent assailant trailed effortlessly behind him. 

To think that he had the terrible luck of being placed on the hit list by someone from the White Rogue's Guild. 

Weaving left and right, the knight observed his surroundings in a panic. There had to be a way. Some way to shake off this pesky hired hand.

A dagger flew past his ear, whistling a sharp tune of death, before lodging itself comfortably in the head of his noble steed.

Time seemed to slow down as the horse buckled underneath him. Soaring into the air, his large frame flew over various bushes and twisted branches before finally breaking out into a clearing.

Nothing but cold night air and pale moonlight surrounded him.

"R-Really now?!" 

Just his luck to fall off a cliff. God damn RNGed forests.

Panic seized his voice as the distance between him and the ground rapidly shrunk. 

It was a fifty meter fall...

Pushing his shield in front of him, Leroy felt his arm buckle slightly against the generated air resistance. 

His shield glowed a brilliant yellow as a strong determination crossed his face.

"N-Not yet. Not before I see her!"

Her face flashed before his eyes as he came crashing towards the ground.

As the durability of his «Knight's Shield» quickly depleted upon receiving the damage dealt by the impact of the fall, large cracks became visible through the brilliant yellow glow that was now dulling.

He watched his health take a minor dip, changing from a darker green to a much weaker and lighter one.

Standing up, he threw his aching arm around. 

There was definitely going to be a nasty bruise.[/quote]
