Some may already know of this trick some may not but I did not see it posted here. Yes, this trick can be very expensive but really worth it PVP wise or bosses/ Death Matches.
First get Mage and your melee character.
Have mage cast I2H over and over untill out of mp
Take melee character and restart and BOOM you have 15 mins of I2H.
Yes Rinse and repeat and you can get this to last for about 2 hpurs if you have the M-GEMS for this.

I will submit the pet Chao trick later on. Currently I am looking for Linex or Linmate 2.0 or something to overide the old linmate junky test thing.
