First You need MacroGamer:

You can set it to check the pixels on your CP bar and when they change colour spam CP pots so you don't even have to toggle a 'CP Spam Button'
Once its installed and running you can create your macro by clicking on the "Create New" button.
Now give your new macro a name and assign a binded key to something you wouldn't normally use ingame during pve, pvp or chat. You must also change the radio option in the bottom right to "Repeat until stopped".
Now the hard work begins. First prepare your Lineage 2 client by setting your gamma to "Average" in the Options > Video setting. You can change it back after you have the macro running.
Now get your CP down. You can do this with a friend but I found it easier to change class. Now alt-tab out of game and back to the macro gamer program. Select "Insert" and add a "pixel event". Now select "Pick Location". You can no longer use your mouse 1 button until you are ready to pick a location on your cp bar so use the keyboard to alt-tab back into game.
Once you are back ingame select a point on your CP bar that you want the CP pot spam macro to activate. If you have a high CP char you may want to set this around 60%, for low CP chars set this around 90%. MAKE SURE THAT THE POINT YOU CLICK ON YOUR CP BAR, YOU ARE WITHOUT CP. Now alt-tab back to macro gamer and you should see a location setting and colour have been inserted into the option window. Tick the option "wait for colour" and double check the colour you see in the window is similar to the colour you clicked on ingame. If you're happy press "Insert", otherwise try again.
Now insert your key press for the first CP pot. I have my CP pots set on F11 and F12 so decide on which F key's you'll use and edit as you need. To do this click "Insert" and select "Key Event". Set the option to "Hold Down" and press the "Record" button followed by your F key of choice, in my example I used F11. Now press "OK".
Now insert the time delay between key presses. To do this press "Insert" and select "Delay". I suggest using the delays I have setup on my screenshot as a guide and take your own initiative when it comes to editting them. Rinse and repeat for the remaining key presses and Delays. To change the order of the macro use the "Move Up" and "Move Down" buttons as required.
Never had a problem with it but use at own descretion
