You need to be quick, agile and cunning when playing a Jester in the online game
PVP Techniques: Jesters rely a lot on their burrowing skills. You need RS Gold to be quick, agile and cunning when playing a Jester. Some of my most used combos:
Stun Lock (Effective against Oracle, War-mages, Myrmidons and Harlequins)
Burrow > Rocket Punch (Success Stun) > Final Decision > Rolling Stinger > Final Decision > Rocket Punch (Success Stun) > wait for cool-down > Continue back from
If you’re Rocket Punch failed to stun the second time, don't panic, just Cut Down while your enemy is getting up and wait below with a Final Decision to continue back your combo.
Finishing Combo (For stylish kill): Final Decision > Rolling Stinger > Final Decision > Rocket Punch (Success / Fail Stun) > Cut Down > wait below and catch it with a Upper Screwdriver > Aerial Combo if he/she is still dangling with a bit of life
Sorry I haven't figure out a combo for Harlequins yet as I have just only reached level 40. But the stun lock combo is good enough for me to kill players 13 levels higher than me when I was still a Jester.
Just remember, when playing a Jester or Harlequins, don't rush. You study your prey first just like a panther.
Stats for Jester/Harlequins: For PVE, AGI and ACC equipments are the best and should be your priority.
