MOBA-games, has these Ulti-skills lets steal it to rsc.

-Hear me out, back in the days i coded servers (way back), i was fairly good at it, and before i quit i had an project going, that was gonna build on rsc-pk with new tweaks.

Explaination/Technical
An "Ulti"-kind-of-skill for a selected/specific class, gotten from a Quest or simly given by npc or w/e.
make an overlay for the skill(kind of like the one in settingsinterface/party) with a timer. Make it always visible.

You choose your Path and are given an number 1-4 in mysql table or w/e this source use.

All skills will have 10minute Cooldown.
-----------
1 Paladin, Bubbleskill (use animation of teleportbubble or waterfall-object over player) which make you invulnerable for ranged,casting,hits for 3 seconds or so.
2 Rouge/Bandit, Invisibleskill until you attack someone. Basicly remove player from updating their xy for lets say 15 seconds? making them invisible.
3 Magician, Teleportskill for a longer distance, lets say 4-5sq of teleport.

This would give pk another level but still keep the rsc-style of things.

------------
How it would be used:
Scenario 1.
An Bandit goes invisible, i would guess prayerbeasts would choose this "path". stalking up on a team by castle kiling their archer.
Scenario 2.
An Paladin, preferably a highlvl pker is about to die in an fight, he activates his bubble on 2nd round giving him another chance to eat/retreat.
Scenario 3.
An Magician, probably a highlevel pker or prayerbeast or Archer would get use of this. either to escape (hoping others dont have the same path) when in a pinch or to catch an opponent far away.

ps. im willing to code the basics of it, if its something people like.
