[Guide] How to Beat Ghostkerchief everytime

[sparkling]

Items Required:
(you need an account to see links)
Engraved Chakram
(you need an account to see links)
Leaf Shield

Steps:
1) Get your pet HP down below 11 by fighting any challengers and then withdrawing.
2) Proceed to fight Giant Ghostkerchief.
3) Use Leaf Shield and Engraved Chakram every turn and Fierce/Berserk Attack.
4) Keep repeating till you beat Ghostkerchief.

Shortcuts:
Type

javascript:function one_submit() { return true }

in your URL bar, then select your two weapons, fierce attack and click go then hold enter till he dies.

Note: This must be done with a certain strength boost for the damage to go through.

Update:
With Engraved Chakram, your pet need to have a boost of 40 or more in Str.
There's a cheaper method using Meteor Rock, your pet need a boost of 55 though (just a guess, I tried and it worked well with 95).
