Background and info Jaecaar is a melee assassin focused on staying out of sight and striking enemies whenever they don't pay attention. Jaecaar does also not use any form of resource
In an isolated part of the lands of Kumungu, there are stories of a creature always leaving behind a trail from it's tail, but no one has ever been able to spot it, instead they found what seemed to be symbols painted in red upon the grounds bearing resemblance to skulls, few have taken the task to try and hunt this creature, but those fortunate enough to survive the hunt tell of a creature that would strike down hunters without ever being spotted, it strikes as quick as it moves and leaves only the bodies on the ground as trails.

When the maximum limit of 3 symbols is exceeded, the oldest symbol disappears, also Jaecaar stores a charge of cursed symbol periodically to a maximum of 2 and a symbol lasts for up to 3 minutes.

Passive: Jaecaar becomes able to move through units, and if he moves through enemy units he will automatically apply on hit effects on them, this can only occur on the same target every 1/0.75/0.5 second. (this does not break his invisibility) Active: Jaecaar becomes invisible for 10/11/12 seconds, also granting him 20/30/40% more movementspeed while invisible. Whenever Jaecaar auto attacks or uses an ability he becomes visible for 1 second. This ability can only be activated when out of enemy sight (if activated while spotted the ability is put on 5 second cooldown.
Cooldown: 100/80/60 seconds
